Using input from Switch to control a loop

[MrRoboto]

Can someone read below, I was told to do this and I am still getting the errors below the code, What am I doing wrong still?

Thank you in advance.



code below:
---------------
switch var PortB.0

main:

if switch =1 then loop 'enter loop
'forward
high PORTB.7 'enable pin
high PORTB.6
low PORTB.5

high PORTB.4
low PORTB.3
high PORTB.2 'enable pin

goto main

loop:
if switch=0 then main 'exit the loop
'backup
high PORTB.7 'enable pin
low PORTB.6 'stop this side
low PORTB.5

low PORTB.4 'reverse this side
high PORTB.3
high PORTB.2 'enable pin
goto loop

By seeing the .pbc extension, I'm I right by saying you have PBC not PBP?

If so... well.. both are WAY different... PBC don't allow direct addressing to a byte/register bit, and so forth for many other command as well.

Who have PBC here?

try this

        SYMBOL PORTB=$06
        symbol TRISB=$86
        POKE TRISB,1 ' PORTB.0 = input, other = output 
        POKE PORTB,0 ' Clear all output
        
main:
        PEEK PORTB,B0
        if BIT0 =1 then goto loop 'enter loop
        'forward
        high 7 'enable pin
        high 6
        low 5
        
        high 4
        low 3
        high 2 'enable pin
        
        goto main
        
loop:
        PEEK PORTB,B0        
        if BIT0=0 then GOTO main 'exit the loop
        'backup
        high 7 'enable pin
        low 6 'stop this side
        low 5
        
        low 4 'reverse this side
        high 3
        high 2 'enable pin
        goto loop

Finger crossed, I don't have PBC

What is the difference of PBC?

How can I get what you have?

Hi,
here's comparision between PBC (PicBasic) and PBP (picBasic Pro)
http://melabs.com/products/comp_pro.htm

Depending where you're living, you can purchase it from the following one

You can also download a limited demo version of PBP.
