FT_ESCCODE()
 Convert Lotus style escape codes

 Syntax

      FT_ESCCODE( <cASCII> )  -> <cPrinterFormat>

 Arguments

     <cASCII> is the ASCII representation of the printer control
                codes in Lotus 123 format (e.g. "27E" for Chr(27)+"E")

                "\nnn" will be converted to Chr(nnn)
                "\\" will be converted to "\"

 Returns

     The binary version of an ASCII coded printer setup string.

 Description

     This function is useful for allowing the user to enter printer
     control codes in Lotus-style ASCII format, and then having
     this function convert that code to the format that the printer
     needs to receive.

 Examples

     cSetup = "15"          // default = Epson compressed print
     UserInput( @cSetup )     // Let user modify setup code
     SET DEVICE TO PRINT      // get ready to print
     ?? FT_ESCCODE( cSetup )  // Output the converted code
