PIC program Error message. Can someone help?

[BABYBASS210]

Hello everyone,

I am trying to program a 16F84 and I am having some difficulties.

What I want to do is change the state of outputs portA and port B at the same time but I get errors when I assemble.

Can someone take a look and please help me out?

Thank you so much.

Sincerely,
Joey Hernandez.

Here is the program:

Correction on the spacing of the program.

Even though the program looks wrong because of the spacings, the spacings where correct the got repositioned when I copied and pasted it to the Electro Tech message body.

Be careful where you place the END statement. All statements are ignored after that.
