PBasic Select Problem

Technical Programming
1

Greetings,
I have chosen to use the new
SELECT construct in PBasic. Here
is the code fragment:

'Dead Reckoning Code
Select stepnum
CASE 0 : gosub go_home
CASE 1 : gosub go_home2
CASE 2 : if rc_sw3 = UP & rc_sw4 = UP then
gosub go_left
else
gosub go_right
CASE 3 : gosub go_forward
CASE 4 : if rc_sw3 = UP & rc_sw4 = UP then
gosub go_left
else
gosub go_right
CASE 5 : gosub go_longforward
ENDSELECT

When I check syntax, it always highlights the stepnum variable and provide the following error:

Expected ‘:’ or end-of-line
Error: 129-Expected ‘:’ or end-of-line

What causes this error ? Searched and couldn’t find anything.

Am running the 2.0 beta 1 editor. It acts like it doesn’t understand the new language features.

thanks in advance.

I had that error once when I had forgot to define a variable.

Have you also checked to make sure that you have included the new PBASIC 2.5 definition at the top?

' {$PBASIC 2.5}

Put that in right below
{$STAMP BS2SX}

But It compains about my constant
definition:

ON con 1

Is ON now a predefined constant ?
Tried using the stamp editor help
to find this out but its useless.

Are the constants ON, OFF, TRUE,FALSE
UP,DOWN now predefined ?

thanks

Yes, most likely they’re reserved. Instead pick a constant that has more meaning, such as ARM_UP, or LIFT_UP, etc.

You’ll also get an error in your code because you didn’t close your if conditions with an ‘endif’

I already fixed the missing ENDIF
problem.

thanks for the heads up.
