Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi all,
Hoping someone can confirm what I'm doing is OK. I had something like the following in a program and it worked fine as a routine, but when I test a cut down version in command mode it always returns 0 for the x parameter(stored in variable a). the y parameter is correct.

Do a=Touch(x):b=Touch(y):If a>-1 And b>-1 Then print a,b ELSE b=b:EndIf:Loop

Same problem evident with 5.04.04 on a standard uMite and 5.03.o on a uMite+

eg. output like
0 162
0 163
...
Hope it's nothing like x being treated as a variable rather than a literal parameter?

...interestingly when i try

Do b=Touch(y):a=Touch(x):If a>-1 And b>-1 Then print a,b ELSE b=b:EndIf:Loop

then the y variable gets lost...
e.g.
234 0
235 0
...

Regards,
Phil

You are missing the colon after "DO"
