i2C_ROMEngine - Help

I seem to be having trouble writing a string to the EEPROM using i2C_ROMEngine.

The following code writes successfully to the rom

[SIZE=3]EEPROMxPORT.ROMEngineStart(29, 28, 0)
waitcnt (10000+cnt) 
EEPromxPORT.writeLong ($7fd0, string("TestWrite))
waitcnt (10000+cnt)
EEPROMxPORT.ROMEngineStop [/SIZE]

However this code writes blanks to the EEPROM. It seems the string is not being passed to the i2C_ROMEngine. I cant figure out why. Any ideas?

[SIZE=3]EEPROMxPORT.ROMEngineStart(29, 28, 0)
waitcnt (10000+cnt) 
bytemove (@TestData, string("TestWrite"))
EEPromxPORT.writeLong ($7fd0, @TestData))
waitcnt (10000+cnt)
EEPROMxPORT.ROMEngineStop [/SIZE]

ByteMove needs the length, and WriteLong writes four long-aligned bytes, so if TestData is a byte array it may not be aligned correctly.
