txt file string (CHANGED)

[Robbo]

ok have a txt file with loads of 1,2,3 bit decimal codes, eg 27 64 27 116 1 27 54, i need to convert this with known Epson Codes for example

Printer Operation:

27 25 48 ESC EM 0 Turn cut sheet feeder control off
27 25 52 ESC EM 4 Turn cut sheet feeder control on
27 56 ESC 8 Disable paper out sensor
27 57 ESC 9 Enable paper out sensor
27 60 ESC < Select unidirectional mode for one line
27 64 ESC @ Initialize printer
27 85 48 ESC U 0 Cancel unidirectional mode
27 85 49 ESC U 1 Select unidirectional mode
27 115 48 ESC s 0 Turn half speed mode off
27 115 49 ESC s 1 Turn half speed mode on

whats the best way to store all these codes, as there is loads more and whats the best way to convert from the decimal to charater
