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.
The X function 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
- The following statement would display
1234
:printText {'f1f2f3f4':x}
