SCRATCH Statement

The SCRATCH statement can be used to reset variables to their default

values, erase the current program, reset the values returned by

functions, or reset the entire interpreter environment.

Syntax

[ALL ]

[PROG]

SCRATCH [COM ]

[VARS]

Parameters

ALL Set the HP Business BASIC/XL interpreter environment to

the same state as that on initial entry following the

BBXL command.

COM Deallocates all variables. Also stops program execution

if the SCRATCH statement is in a subunit.

PROG Erases the current program in the interpreter's work

space. PROG is the default option set for SCRATCH.

VARS Deallocates all variables except those in common areas.

Also stops program execution if the SCRATCH statement is

in a subunit.

The options used with the SCRATCH statement permit you to select the

level of features to be reset. Thus, SCRATCH VARS resets only those
