Using "exists()"
-
Will "exists()" evaluate a string expression? Here's my example that I would use in a macro that is passed a numberic value for "T":
if exists("global.wiper_hgt_T" ^ param.T)
...The variable I want to check existence of is global.wiper_hgt_T0

@generisi I suspect not, because the function takes a variable name (no quotes) as an argument, not a string. I could imagine it being useful, though.
