INC

Adds a value to a variable. Works on numbers and strings.

Syntax

INC number_variable [, amount]
INC string_variable$, string$

INC variable, amount is a shorter way of writing variable = variable + amount (similar to variable +=​ amount in other languages). amount is 1 if omitted.

When used on strings, INC works the same as PUSH (but slightly faster). Either way is more efficient than + because they modify the string rather than making a copy.

Examples

X=13
INC X
PRINT X '14

S$="abc"
INC S$,"defg"
PRINT S$ 'abcdefg

Version Information
