DATA statements with PIC16F88

I am using PBP2.50c with MCSP 3.0.0.5 with MPASM 5.03. The target PIC is the 16F88.

I always try and store the latest program revision number in the first 50 or so bytes of EEROM and display this on startup. It works a treat with 18F4620 which is my main PIC chip.

I now find code that works fine on the 18F4620 will not work at all on the 16F88.

The following code should output repeatedly two different lines of text. The first should be the data stored in EEROM locations 0 to 54 and the second line should be "This is a test of the TouchPad serial output".

All I get is the second line with the software revision line being just a string of blank or unprintable characters.

Are there any special requirements for the DATA statement with a PIC16F88?
