missing label

Robert.IT

When I go to run and check the syntax, it highlights the word CON in my code and says label missing. How can I Fix this?

Can you give us a sample of your code?· This will allow us to see what you
trying to do.

CON is not a keyword in $PBASIC 1.0 syntax -- if you're using a BS1 then you must use SYMBOL for everything. If you're writing a program for the BS2 family, make sure you're syntax level is set to 2.0 or 2.5.

First thing I see is your declaring a BS1 in your first line, yet the comments say its a bs2 program.· I think the CON works only on the BS2 and higher.

You're telling the editor that you want to program a BS1, yet you're using BS2 code. Change your module definition to {$STAMP BS2}. You can also change the servo and whisker defintions to PIN, but be sure you're using 2.5 syntax. In short, put these lines at the top of your program:

' {$STAMP BS2} -- this replaces current definition
' {$PBASIC 2.5} -- this allows PIN and other programming conveniences (see help file)
