STEP
Abbreviation: ST <SHIFT+E>
TYPE: Statement
FORMAT: [STEP <expression>]
Action: The optional STEP keyword follows the <end-value>
expression in a FOR statement. It defines
an increment value for the loop counter variable. Any value can
be used as the STEP increment. Of course, a STEP value of zero
will loop forever. If the STEP keyword is left out, the increment
value will be + 1. When the NEXT statement
in a FOR loop is reached, the STEP increment
happens. Then the counter is tested against the end-value to see
if the loop is finished. (See FOR statement
for more information.)
NOTE: The STEP value can NOT be changed once
it's in the loop.
EXAMPLES of STEP Statement:
25 FOR XX=2 TO 20 STEP 2 (Loop repeats 10 times)
35 FOR ZZ=0 TO -20 STEP -2 (Loop repeats 11 times)
