PROGRAM( ) Function

Example   See Also

Returns the name of the program currently executing, the current program level, or the name of the program executing when an error occurred.

Syntax

PROGRAM([nLevel])

Returns

Character or Numeric

Arguments

nLevel

Specifies how many program levels back the program name is to be found. This parameter can range from 0 to the program nesting depth. A program can execute another program which can execute another program, and so on. Programs may be nested to 128 levels.

If you specify 0 or 1 for nLevel, PROGRAM( ) returns the name of the master program (the highest-level program). If nLevel exceeds the program nesting depth, PROGRAM( ) returns an empty string.

If you specify –1 for nLevel, PROGRAM( ) returns as a numeric value the current program level. PROGRAM(–1) always returns zero when issued from the Command window.

Remarks

PROGRAM( ) helps your program recover from errors. It is similar to SYS(16).

If used without an argument, PROGRAM( ) returns the name of the currently executing program.
