Description

The FOR ... NEXT command repeats the commands between the FOR and the NEXT statement. The <exp1> specifies the loop start point and <exp2> the loop end point. <exp1> and <exp2> may be integer or date values. The FOR...NEXT command is equivalent to a counter based DO WHILE ... ENDDO set of commands but FOR ... NEXT is faster.

STEP <expN>

If the optional STEP <expN1>, is specified, then the FOR ... NEXT loop will increment by <expN1>. This value can be a positive or negative number. If <expN1> is not specified then the FOR ... NEXT loop will increment by 1.

EXIT

The looping will continue until either <expN2> is reached or an EXIT command is encountered.

LOOP

If a LOOP command is encountered, then control returns to the start of the FOR ... NEXT loop.

Example

for i = 1 to 10 step 2
    ?i*2
next
