_DEFINE lets you define a range of variables according to their first character as a datatype.
Syntax: _DEFINE range or letter[, range2 or letter2[, range3 or letter3[, ...]]] AS [ _UNSIGNED ] datatype
- 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.
Example:
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.
