Title: Question about usage of the GetCalc() command.
Post by: Link on August 30, 2012, 01:27:44 pm

Okay, I created a new appvar using GetCalc like so:

Code: [Select]

GetCalc("appvTest",100)->T
In my other programs, how do I check if this App-var has already been made? Will it work by using the If command? or something else?

GetCalc(PTR)
Finds the object who's name is pointed to and returns a pointer to the start of its data, or zero if it was archived or not found.

I hope this helped you. :)

Yes, it's in Commands.html: GetCalc("appvTest") will return the pointer to it if it exists, else 0.

Not exactly. It returns the pointer if it exists and if it is unarchived, and 0 if it is archived or if it doesn't exist ;)

So what you may need is something like

  UnArchive "appvTEST"
  .does nothing if the appvar doesn't exist
  GetCalc("appvTEST")->V
  !If
   GetCalc("appvTEST",100)->V
  End

To be sure it is in RAM ;)

Close enough :P I always forget about archived stuff.

(By the way, you can save twelve bytes by saving "appvTEST" to Str1 or something.)
