Where is the bug ?

Try this simple program with a bicolor LED between pins 11 & 0 on a BS HW Board.
In the·"FOR" statement, if the TO 270 is changed to 260 or less the
program executes the correct number of times, a value of 270 or
greater causes the program to go into an endless loop. WHY?



' {$STAMP BS2}
' {$PBASIC 2.5}
' usig a bicolor led between pins 11&0
counter VAR Byte
FOR counter=0 TO 270 STEP 10
HIGH 11:LOW 0 'pin 11 hi pin 0 lo
PAUSE 50
LOW 11:HIGH 0 'pin 0 hi pin 11 lo
PAUSE 50
NEXT
END

using BYTE as the variable type only allows 256 possible values.
try using WORD as the variable type instead, allowing 65536 values.

hope this helps

That was the answer, good job, and thank you

counter is defined as a byte which gives you 256 possibilities, and wraps around to zero before it hits the elusive 270.
