A couple of similar functions I translated to Script BASIC from Business BASIC.

Code: Script BASIC
  1. FUNCTION BB_ATH(HexStr)
  2.   LOCAL LenHex, AsciiStr, HexTable, ScanPos, HiByte, LowByte
  3.   LenHex = LEN(HexStr)
  4.   IF LenHex % 2 = 0 THEN
  5.     HexTable = "0123456789ABCDEF"
  6.     FOR ScanPos = 1 TO LenHex STEP 2
  7.       HiByte = INSTR(HexTable,UCASE(MID(HexStr, ScanPos, 1))) - 1
  8.       LowByte = INSTR(HexTable,UCASE(MID(HexStr, ScanPos + 1, 1))) - 1
  9.       IF ISINTEGER(HiByte) AND ISINTEGER(LowByte) THEN
  10.         AsciiStr &= CHR(HiByte * 16 + LowByte)
  11.       ELSE
  12.         AsciiStr = ""
  13.         GOTO Exit_For
  14.       END IF
  15.     NEXT ScanPos
  16.     Exit_For:
  17.   ELSE
  18.     AsciiStr = ""
  19.   END IF
  20.   BB_ATH = AsciiStr
  21. END FUNCTION
  22.  
  23. FUNCTION BB_HTA(AsciiStr)
  24.   LOCAL AsciiLen,ScanPos,HexStr
  25.   AsciiLen = LEN(AsciiStr)
  26.   IF AsciiLen THEN
  27.     FOR ScanPos = 1 TO AsciiLen
  28.       HexStr &= RIGHT("0" & HEX(ASC(MID(AsciiStr, ScanPos, 1))),2)
  29.     NEXT ScanPos
  30.   ELSE
  31.     HexStr = ""
  32.   END IF
  33.   BB_HTA = HexStr
  34. END FUNCTION
  35.  
  36. hstr = BB_HTA("0123456789ABCDEF")
  37. PRINT hstr,"\n"
  38. PRINT BB_ATH(hstr),"\n"
