JCShell - Data entry/reference

Data for commands and variables can be entered in form of 'HEX[|CHARS[|HEX...]]', where:

HEX: is sequence of pairs of hex digits forming a byte sequence.
CHARS: is sequence of charaters. Their ASCII encoding forms a sequence of bytes.
|: The | switches modes (HEX/CHARS).

In addition, nested elements of the form `#(...)' are parsed. Instead of "()" characters, you can also use the braces [], {}, <>. The "#" element is replace by the number of bytes enclosed in the matching braces.

Examples:

 "0102|ab|03 04|cd"    ==> 01 02 61 62 03 04 63 64
 "01#(|ab|#{FE FF})"   ==> 01 05 61 62 02 FE FF
