An #Warn error needs to be identified and handled

[ineuw]

I have no clue how to deal with this error. I've read the #Warn help page, but I was unsuccessful to implement it to sidestep this.

First of all, #warn-ings are not errors. Warnings are about potential causes for errors... on first glance I didn't even know why it would warn you about the variable in_len, since this variable seems to get assigned in your script before it gets read.

But then there is the line #if out_len := (in_len +4) which probably doesn't do what you expect anyway. Please remove it - in its current form, it doesn't make sense.

Perhaps you meant instead

Code: Select all

if (out_len = (in_len +4) )

As you probably know, the #if directive is only used for creating (or disabling) context-sensitive hotkeys and hotstrings... you seem to try to use it as a regular if-check... but even then you shouldn't use the := assignment operator, but the = operator. At the moment, this expression (almost) always evaluates to true, as it just assigns a non-zero value to a variable.

But the actual problem is most likely this special behaviour of the #if-directive:

The expression may also be evaluated whenever the program needs to know whether the hotkey is active.

That means, the #if out_len := (in_len +4) line may be executed even before in_len is first assigned in the Alt+F12 hotkey (which happens in line: in_len := strlen(in_put) ). In this case, the warning would be issued...

Luckily, the (corrected) line if (out_len = (in_len +4) ) - without a directive - wouldn't be affected by this problem, as it would be executed only after in_len has been assigned.

gregster, much thanks again, it makes perfect sense after your explanation.
