or if you really like to run things together:

if (rc_dig_in06 == 0) pwm01=254 else pwm01=127;

umm... no. There should be a semicolon after the 254 - it is the end of an instruction. the correct format is this:

if(rc_dig_in06 == 0)
    pwm01 = 254;
else
    pwm01=127;

(you can always rearrange that however you wish with tabs, spaces, and line breaks)

Remember, the if-else statement is a control structure, and thus does not count as part of a single instruction. The two instructions here are "pwm01 = 254" and "pwm01 = 127", each of which needs to be ended with a semicolon as shown.

You may have been confused with the colon because of the if-else shorthand notation - for instance, the code below does the exact same thing as the longer if-else below:

pwm01 = ( rc_dig_in06 ? 127 : 254 );

if you are new to programming, though, stick with the longer if-else statement, as it is easier to read and use.
