X (String function)

Hex constant method (String class)

X is an intrinsic function that returns the unencoded value of a hex-encoded string. It is a compile-time-only equivalent of HexToString. Since, in use, it acts like a hex constant, it is also documented with the "Constant methods".

X treats each input character as an input hex digit.

Syntax

%outString = string:X

Syntax terms

%outString	A string variable to receive the unencoded value of the method object string.
string	A hex-encoded string value.

Usage notes

• As in all "Janus Soap" system methods with string outputs, the output %outString variable provides longstring behavior. However, this adds 28 bytes of VTBL usage to every X constant.
• Although its utility is dubious, the following is valid and sets %x to x'01':

  %x = 'f0f1':x:x

• X requires a method object string with an even number of bytes.
• X is available as of "Sirius Mods" Version 7.3.

Example

1. The following statement would display 1234:

   printText {'f1f2f3f4':X}
