Check if global variable exists fails

admin · June 6, 2019, 8:53pm

You can check if a variable is defined this way:

Set !errorignore to true
use the variable, e. g. with store
Check the result with !LastCommandOK

Check if defined: (Since this is a global variable, it is defined at the second run of the macro, because we define it after the check!)
