Revision as of 20:24, 17 October 2009 by imported>Clippy

**_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

- 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.

*See also:* DIM, DEFSTR, DEFLNG, DEFINT, DEFSNG, DEFDBL, _UNSIGNED, ABS, SGN
