# Directives

LONG_FORM | Use Long Variable Names

## Format

LONG_FORM

## Description

Use the LONG_FORM directive to have the PxPlus compiler's input parsing routine accept long variable names (default mode). The complementary directive is SHORT_FORM, which allows only short variable names.

You can write programs in either SHORT_FORM or LONG_FORM or a combination of both. You can also run programs in either mode.
