Hi...Suppose you construct a subroutine in which a variable is set to a particular value. Is that value available everywhere else in the rest of the program? Thanks. playfullscientist

Yes, the concept of local variables is very new to AutoHotkey. In any regular label (hotkey and hotstring definitions count), all variables are global. Only in functions is there a distinction between global and local variables. As an example, this function will not make its variable global by default:

Code:
assign()
msgbox,%variable%
return

assign()
{
   variable = Lorem Ipsum
   return
}


However, this label will:

Code:
gosub,assign
msgbox,%variable%
return

assign:
variable = Lorem Ipsum
return


You can learn more about this behavior by reading the Functions section in your help file.
