tables using PBP and asm command retlw

[queenidog]

I'm working on a 32 bit POV project and have the hardware all sorted out and tested with a small PBP program that sends out Ascii characters from a string "This is a Test". I used the LOOKUP command to read the bytes and output to the 32 light-thingy which I verify is displaying four bytes of Ascii text.

Now it's time to send an actual drawing of sorts using a bigger table (more than 14 bytes in "This is a Test"). My table is 255 bytes long and I get the dreaded "unable to fit variable" error because page boundary limitation.

I read many posts on this forum and Google search and see various ways around the issue but I don't know which is easiest or applicable.

I saw a method where the user created a table (the program was all in assembler) that began like this:

ImageData ADDWF PCL,F
; Page boundary, image data starts here. There are 255 rows each one byte long
RETLW B'10101010'
RETLW B'11111111'
RETLW B'00000000'

Can I jump to this table with a Call? How do I integrate the two programs (one in PBP and the other-the data table-in assembler)?
What housekeeping, initialization do I have to do to get the programs working together?

Can I/should I/ use Writecode-Readcode per Melanie's document? Isn't RETLW easier? Data is constant, not variable.

I haven't done any assembler programming with this PIC 16F628 and just started with PicBasic Pro.
