Convert from hexadecimal to byte string

Note: Many $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Lstr_X2C function is the HexToString function.

This function converts from a hexadecimal encoded string to the decoded byte string. It is identical to $X2C, except it is longstring capable.

The $Lstr_X2C function accepts one argument and returns a string result whose hexadecimal encoding is that argument.

The first argument is a Longstring which is a hexadecimal encoding.

The returned value is the hexadecimal decoding of the argument string. If the argument is not a valid hexadecimal encoding, the null string is returned.


%decoded = $Lstr_X2C(string)

%decoded is set to the hexadecimal decoding of string.

usage notes

  • You can check for an invalid hexadecimal encoding by checking for the null string return value from $Lstr_X2C. Of course, if it is possible that the argument is null, the null string is a valid returned value. If you need to check for errors, and the null string is a possible argument value, you can use an approach such as the following:

    %STR = $Lstr_X2C(%IN) IF %STR EQ '' IF %IN NE '' THEN error code ... END IF END IF

  • $Lstr_C2X is the inverse of $Lstr_X2C.


The following code would print Red rum, which is the character representation of the EBCDIC characters represented in hexadecimal as "D985844099A494":

PRINT $Lstr_X2C('D985844099A494')
