Important Notice
The pages on this site contain documentation for very old MS-DOS software,
purely for historical purposes.
If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.

Variable Names
BASIC Variable Names
A variable name cannot be a reserved word, but embedded reserved words are
allowed. Reserved words include all BASIC commands, statements, function
names, and operator names.
Variable names must also be distinct from SUB and FUNCTION
procedure names and symbolic constant (CONST) names.
ISAM Variable Names
Some parts of an ISAM database require names (e.g. tables, columns, and
indexes), and these names must conform to the ISAM naming convention.
The ISAM convention is a subset of the BASIC convention.
