As Sayzer is hinting, if your data does not change after you do the initial programming, you could use the LOOKUP or LOOKUP2 command. (or just the READCODE command referenced below if you preloaded your data)

If your data is going to change, you could use WRITECODE and READCODE. Also see: http://www.picbasic.co.uk/forum/showthread.php?t=137 for reference
