I seem to have run into a rather odd crash trying to make my first OBSE mod. It's pretty simple, just making keyboard shortcuts for various menus. Using GetMenuFloatValue with a format string longer than 45 characters causes CS to crash when saving the script. If I insert gibberish into the format string I can make it as long as I want, but using the real format string crashes when it goes over 45 characters.

Here's the applicable code (this is repeated for the other buttons, I didn't think it necessary to include all of them). If I cut the format string for GetMenuFloatValue down to 45 characters it saves fine but anything more and it causes CS to crash.

if (isKeyPressed3 25 ) ; Persuade    set buttonVisible to GetMenuFloatValue "dialog_topics\dialog_button_layout\dialog_persuade\visible" 1009    if (buttonVisible == 2)        ClickMenuButton "dialog_topics\dialog_button_layout\dialog_persuade" 1009    endif    set curKey to 25elseif...

Any help would be appreciated. The mod will work without that function but it causes some buggy behavior.

It's the so-called 73-Byes Bug which causes the CS to crash when saving the Script if the uncompiled (?) size of the calculation/function/whatever is on the right side of to is greater then 73 Bytes. This also happens if the size of an if-statement is greater then 73 Bytes.

Solution: use http://www.obse.silverlock.org/obse_command_doc.html#Let instead.
If this happens using an if-statement use a dummy-variable and assign the value using let.

A buffer overflow occurs when the vanilla expression parser (used by SET and IF) converts an expression to postfix notation and the compiled data exceeds 73 bytes. This has been fixed by CSE.

Thank you both, it works great with LET instead of SET.
