LCDout
I am getting
error line 38 bad token "|" and
error line 38 bad expression on my LCDOUT line. I copied & pasted it from the manual. Any suggestions?

LCDOUT $FE, 1, “Hello”

Your double quotes around “Hello” look odd. Cut & paste this directly into your code and see if that helps.
LCDOUT $FE, 1, "Hello"

That was the fix, I was lucky enough to figure it out before your reply, but its good to have it documented for others in the future.
Now that its compiled and programmed, I am still having no luck with the Hello displaying on the LCD.
With the code above on a 16F737 I get one solid black block in the first character location and a blinking cursor in the second character location. all others are blank. Can anyone deduce what is causing this problem?
I am using a 4bit mode to the LCD and it is wired just as the picbasic manual says in the LCDOUT subsection
-
And of course since the PICBasic manual example uses PORTA and you're using a PIC16F877A which has Comparators and ADC's you remembered to switch PORTA into DIGITAL mode?
-
I actually misspoke. I was using a 877a until I fryed it, now I am using a 16f737.
I will research the digital IO. I thought they were digital by default. I am also using portb, as I redefined in my code.

OK... if you have it wired as per your DEFINEs... then add PAUSE 1000 before you do your first output to the LCD... most LCD's need time to wake up following a power-on, you could be throwing data at it before it's ready and initialised.

no luck,
I also put in an indicator light at the beginning of the code so I knew it was executing.
