Type Declaration Suffixes Append one of the following type-declaration suffixes to the variable name: %, &, !, #, $. The dollar sign ($) is the type-declaration character for string variables. You can assign a string constant to the variable of up to 32,767 characters, as in the example below. A$ = "SALES REPORT" Numeric-variable names can declare integer values (denoted by a % suffix), long-integer values (denoted by a & suffix), single-precision values (denoted by a ! suffix), or double-precision values (denoted by a # suffix). Single precision is the default for variables without a type suffix. There is no type declaration character for a user-defined type.
