A programming question

cedtinsi

Thank You and Welcome.

I have a programming concern.

Can I use multiple conjonctions in a statement?

I mean something like:

DO
LOOP UNTIL (IN1=1)OR (IN2=1)OR (IN3=1)OR (IN4=1)

Can the Basic Stamp read and execute that?

Please, as always, your help will be appreciated.
Thanks.

Yes, please see the STAMP manual for basic syntax questions.

' {$STAMP BS2}
' {$PBASIC 2.5}
i VAR Byte

MAIN:
i=0
DO
  DEBUG "Hello World"
  i=1
LOOP UNTIL ((i=1) OR (i=2))
END

First, Thank you for your help Sir.

I consulted the Basic Stamp Manual before asking the question.
I am sorry for any misunderstanding; but my question is: can I use multiple OR's or AND's in a conditional statement?
I mean, more than one OR or one AND; what is the maximum I can use?

{$STAMPBS2}
{$PBASIC 2.5}

i VAR Byte

Do
i=i+1
DEBUG " * "
LOOP UNTIL ((i=1) OR (i=2) OR (i=3) OR (i=4))

can I do that?


Again, thank you.

Yes, you can do that. The maximum number, for practical purposes, is unlimited. Keep in mind that each term (like "OR i=4") takes some BS2 memory and that is the limiting factor. Also, the entire expression is evaluated before the UNTIL is executed. If you have a lot of terms, this can slow your program down.
