Updating multiple variables in case statement - case

I've been looking around for a while so forgive me if maybe I'm using improper terminology...
The goal of the code is to update Aout1 and Aout0 if the input is 0, with the output corresponding to a 7-segment display, but I'm getting the following error:
"Error (10170): Verilog HDL syntax error at FourBitAdder.v(55) near text: ","; expecting ";". Check for and fix any syntax errors that appear immediately before or at the specified keyword."
Below is a snippet of the code giving me issues...
always #*
case (A)
4'b0000 : Aout1 = 7'b1000000, Aout0 = 7'b1000000; //00
I tried changing the code to the following and while I didn't get any errors on my software, my hardware (7-segment display) isn't working like it was when I was trying to just change one variable per case.
always #*
case (A)
4'b0000 : Aout1 = 7'b1000000; 4'b0000 : Aout0 = 7'b1000000; //00
Thank you in advance :)


Use a begin and end statement after the colon.
always #* begin
case(A)
4'b0000: begin
Aout1 = 7'b1000000;
Aout0 = 7'b1000000;
end
4'b0001: begin
Aout1 = 7'b0000011;
Aout0 = 7'b0000011;
end
endcase
end

Decimal points to Hexadecimal Conversion in Verilog

I am working on a verilog code. I am completely new to verilog.
Suppose, I have to represent 0.6072529350088814 in hexadecimal, its value comes out to be 32'h26dd3b6a, as shown in code on the below :
https://electronics.stackexchange.com/questions/354594/cordic-algorithm-using-verilog
But I donot understand how this conversion works?
Suppose I want to display the value and see it in decimal, what should be code?
`timescale 1ns / 1ps
module top(
);
wire signed[31:0] init_value= 32'h26dd3b6a; // 0.6072529350088814
always#(*)
begin
$display("The init_value= %d", init_value);
end
endmodule
I have tested the above line of code, but this does not work.
The value of the init_value is displayed as
The init_value= 652032874
I expect that result should be 0.6072529350088814.

Code:
$display("The init_value = %f", $itor(init_value) / (2 ** 30));
Prints:
The init_value = 0.607253
I am not sure if the code under the link is correct. Theoretically, the conversion should be done through 2 ** 31 or 2 ** 32.

TypeError: argmax(): argument 'input' (position 1) must be Tensor, not str

My code was working fine and when I tried to run it today without changing anything I got the following error:
TypeError: argmax(): argument 'input' (position 1) must be Tensor, not str
Would appreciate if help could be provided.
below is the code snippet where I am getting an error. I am using BERT mdoel
start_scores, end_scores = model(torch.tensor([input_ids]), # The tokens representing our input text.
token_type_ids=torch.tensor(
[segment_ids])) # The segment IDs to differentiate question from answer_text
# ======== Reconstruct Answer ========
# Find the tokens with the highest `start` and `end` scores.
answer_start = torch.argmax(start_scores)
answer_end = torch.argmax(end_scores)

In your line of code
start_scores, end_scores = model(torch.tensor([input_ids]),token_type_ids=torch.tensor([segment_ids]))
you have to make it:
start_scores, end_scores = model(torch.tensor([input_ids]),token_type_ids=torch.tensor([segment_ids]), return_dict=False).
It worked for me. I had the same problem.

Inputbox and cases, cancel or closing the window

I'm new to autoit, and I'm wondering how to deal with some things. The code is simply this line :
$input = InputBox("game : +/-", "Write a number:")
If I write a number in the section, the program goes normaly.
If I click the cancel button, an error is thrown and so I dealt with it with :
If (#error = 1) Then
$End = True
Is what I ve done okay?
And :
Could you please explain what is going on here and what exactly is happening if I enter no value or if I press cancel?
If I close the windows, what happens ? I'd like the program to end.
Thank you very much ! Sorry if my question is easy or useless, I'll help me a lot

with a couple of ternary ops you can see that the cancel button sets the error flag and it does =1 or ==1 or =True (because True evaluates to 1)
$input = InputBox("game : +/-", "Write a number:")
$result = (#error == 1) ? 'cancel was pressed' : $input
msgbox(0, '' , $result = '' ? 'empty string' : $input)

When you call the InputBox function values are returned to indicate the result of the process these are:
Success: the string that was entered.
Failure: "" (empty string) and sets the #error flag to non-zero.
#error: 1 = The Cancel button was pushed. 2 = The Timeout time was
reached. 3 = The InputBox failed to open. This is usually caused by
bad arguments. 4 = The InputBox cannot be displayed on any monitor. 5
= Invalid parameters width without height or left without top.
So essentially that means that if it returns a non-empty string, the "success" case, you don't have to worry about #error. If any non-zero value is returned, the value of #error will indicate what has happened. So if in the case of an error you just want to return, you should use this if statement:
If (#error <> 0) Then
$End = True
This works because we know if #error == 0 then the input box has been successful and a value has been returned, otherwise we know it's thrown one of the errors listed above. I would anticipate that closing the window has the same effect as pressing cancel, i.e. #error == 1 but I haven't checked.
Further to this, if you wanted to you could switch on the value of #error and use that to give the user an error message along the lines of "please enter a value" or "command timed out" but that seems more than is required in this instance.
Here's the relevant documentation: https://www.autoitscript.com/autoit3/docs/functions/InputBox.htm
Good luck!

Scilab - gui - many unknown variables error messages

Still trying to understand the logic of Scilab, I created a small calculation tool for a mechanical element. The main problem I have is finding the right order (or syntax) for the calculation code... I get a lot of "unknown variable" errors and I don't understand why?
I tried to change the order of definitions for the functions, declare the variables as global, etc. but nothing seems to help.
The code for the calculation is not long and also not complicated, but the gui was built using guibuilder, so the uicontrols definitions are probably much longer than they need to be.
Could somebody help me make this code working, as I would learn and understand a lot by this example, althought it contains more than one "problem zones"?
Here what I've done:

I expect the code to dynamically update the graph and the parameters table according to the positions of input sliders and popup-menu.
Again, it would be very helpful if somebody could help me get this code working, as I would get answers for a lot of my questions concerning programming with scilab.
Thank you very much in advance!

First of all, your code is not directly executable, caused by the linebreaks. Please add ... after each line of a statement. This improves also the readability.
As mentioned by #luispauloml, you try to use variables, which exist just inside of another function. For example you try to reach table_param, which is just alive in tab_param_callback(handles).
To get rid of this, you have to define the output for the function:
function [table_values, table_param] = tab_param_callback(handles)
table_values = string([ wd Wp Talwd Malwd alphaalwd]);
table_param = [table_titles; [table_values]];
endfunction
Now you can call this function to get the variable:
string(tab_param_callback(handles))
I corrected just this case and added the dots as explained. For the other variables, it can be done analogously. Furthermore, I moved the function definition to the beginning of the code. Because if your scrips crashed in the middle, the compiler has no chance to read the function definitions.
Please find the code in this file .
I hope this helps. Good luck!

Exploding a string ASP

I have the following which is returned from an api call:
<WORST>0</WORST>
<AVERAGE>93</AVERAGE>
<START>1</START>
I need to parse this to just give me the <AVERAGE></AVERAGE> number, 93.
Here's what I'm trying but get error detected:
res = AjaxGet(url)
myArray = split(res,"AVERAGE>")
myArray2 = split(myArray[1],"</AVERAGE>")
response.write myArray2[0]
I'm brand new to ASP, normally code in PHP

VBScript doesn't recognise square brackets [] when accessing Array elements and will produce a Syntax Error in the VBScript Engine.
Try making the following changes to the code snippet to fix this problem;
res = AjaxGet(url)
myArray = split(res,"AVERAGE>")
myArray2 = split(myArray(1),"</AVERAGE>")
response.write myArray2(0)
On a side Note:
Parsing XML data in this way is really inefficient if the AjaxGet() function returns an XML response you could use the XML DOM / XPath to locate the Node and access the value.
