Hex constant method (String class)
This intrinsic function returns the unencoded value of a hex-encoded string.
It is a compile-time-only equivalent of the HexToString method.
Since in use the method acts like a hex constant, it is also
documented with the Constant methods.
The X function treats each input character as an input hex digit.
The X method is available as of Sirius Mods version 7.3.
Syntax
%outString = string:X
Syntax terms
| %out | 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 %out string variable provides longstring behavior. This adds 28 bytes of VTBL usage to every X constant, however.
- Although its utility is dubious, the following is valid and sets %x to 'X'01:
%x = 'f0f1':x:x
- The X function requires a method object string with an even number of bytes.
Example
The following statement would display '1234':
printText {'f1f2f3f4':x}
