You code for setting PCLATH looked OK.  The best way to get PCLATH set would
be with the PAGESEL directive.

>                movlw   HIGH (page_1)   ; move high byte of page_1 sub
>                movwf   PCLATH          ; address in to PCLATH
>                call    page_1          ; call funtion in page_1
>                call    send_ascii      ; print "1"

This fails because PCLATH is still set to page 1 when SEND_ASCII is called.
