INC and INCF

Statements

SYNTAX: INC variable

INCF variable

PURPOSE: To increment a variable by one (INC) or four (INC F). INCF is usually used to increment a pointer

for floating point number storage.

REMARK S: This is a fast increment of a simple or array variable.

A= A+ 1 slow

INC A fast

A= A+ 4 slow

INCF A fast

INC executes more than double the speed of the statement it replaces. Valid for simple and array

variables.

RELATED: DEC, DECF

EXAMPLE: 10 PRINT H

20 INC H

30 PRINT H

RUN

Line 10 increments element 8 of the array A.

10 INC A(8)

INCF is used to increment a pointer to a floating point number. The following example stores 15

floating point numbers to RAM segment 1.

fptr = &1000

do 15

a = ain(0) *.00232

fpoke fptr,a,1

incf fptr

enddo

ERROR: < Expected variable> – if parameter is not a variable
