DEFINE

_DEFINE defines a range of variable names according to their first character as a datatype.

Syntax

_DEFINE range or letter[, range2 or letter2[, range3 or letter3[, ...]]] AS [_UNSIGNED] datatype

Description

• Variable start letter range is in the form firstletter-endingletter (like A-C) or just a single letter.
• Datatypes: INTEGER, SINGLE, DOUBLE, LONG, STRING, _BIT, _BYTE, _INTEGER64, _FLOAT
• Can also use the _UNSIGNED definition for positive numerical values only.

Examples

_DEFINE A-C, F AS _UNSIGNED INTEGER

Explanation: Any undefined variables that start with the letters A, B, C or F will now be defined as unsigned integers. Unsigned integers can only use positive values while ordinary integers can also use negative values.
