Demo Program (FOR-NEXT.bs2)

' FOR-NEXT.bs2

' This example uses a FOR...NEXT loop to churn out a series of sequential

' squares (numbers 1, 2, 3, 4... raised to the second power) by using a

' variable to set the FOR...NEXT StepValue, and incrementing StepValue

' within the loop. Sir Isaac Newton is generally credited with the

' discovery of this technique.

' {$STAMP BS2}

' {$PBASIC 2.5}

square VAR Byte ' FOR/NEXT counter

stepSize VAR Byte ' step size increases by 2 each loop

Setup:

stepSize = 1

square = 1

Main:

FOR square = 1 TO 250 STEP stepSize ' show squares up to 250

DEBUG DEC ? square ' display on screen

stepSize = stepSize + 2 ' add 2 to stepSize

NEXT ' loop until square > 250

END

NOTE: This example program can be

used with all BS2 models by changing

the $STAMP directive accordingly.
