please help. 3x. | a***f

variable named "var" that is
defined in the current scope (scope is where you are running in the current
"call stack" - what routine
call you are currently running in) into 'myArray'.
2. Use EXECUTE, which cannot be compiled in a .sav Runtime program:
EXECUTE treats its string argument as a command th
