Repeat command blocks

[jens]

Hello

Does anyone have an idea on how to repeat a block of commands a number
of times? I have gone through the E-Basic but I can't get the
Do...Loop or For...Next commands to work for me.

Example:

IF c.getAttrib("bet") = 1 THEN
WritePort &H378,64
sleep 5
WritePort &H378,0
sleep 5

*repeat 5 times

ELSEIF c.getAttrib("bet") = 2 THEN
WritePort &H378,64
sleep 10
WritePort &H378,0
sleep 10

*repeat 5 times

END IF

Ha,
Sorry to other people whom I haven't replied to yet. I saw loads of code and my flu told my brain that I shouldn't bother. Perhaps the flu is rampant at the PST headquarters too? Anyway, this however, we have sorted out quickly.

DIM I as INTEGER
IF c.GetAttrib("bet") = 1 THEN
FOR I = 1 to 5

WritePort &H378,64
sleep 5
WritePort &H378,0
sleep 5

NEXT I 'thus repeats 5 times
ELSE
FOR I = 1 to 5

WritePort &H378,64
sleep 10
WritePort &H378,0
sleep 10

NEXT I 'thus repeats 5 times
END IF

There's prettier ways to code this, such as
Dim I as integer
FOR I = 1 to 5
WritePort &H378,64
sleep cInt(c.GetAttrib ("bet")) * 5
WritePort &H378,0
sleep cInt(c.GetAttrib ("bet")) * 5
NEXT I 'thus repeats 5 times
NEXT I

But one might question the soundness of why you'd want this in the first place, but there you go. (as an aside to David: I'm going for tab indentation, you can see windows has set that to 6 spaces, but I'm addicted to emacs style tab indentation)
Cheers,
Mich

Thank you very much, it works perfect.


"...one might question the soundness of why you'd want this in the

Yes one can. I'm using this to toggle an electrical stimulator on and
off using different segment widths for different situations.


Best,
Jens
