'''Eval''' - Evaluates a mathematical expression

VALUE1/A, OP, VALUE2/M, TO/K, LFORMAT/K
<nowiki>
VALUE1 - value 1: can be decimal, hexadecimal or octal (see below)
OP - a supported operator (see below)
VALUE2 - value 2: can be decimal, hexadecimal or octal (see below)
TO - filename where to redirect eval result
LFORMAT - formatting string used to print the answer (see below)</nowiki>
About VALUE1 and VALUE2:

* Hexadecimal numbers are indicated by either a leading Ox or #x.
* Octal numbers are indicated by either a leading 0 or a leading #.
* Alphabetical characters are indicated by a leading single quotation mark (`) and are evaluated as their ASCII equivalent.

The LFORMAT keyword specifies the formatting string used to print the answer.
You can use %X (hexadecimal), %O (octal), %N (decimal), or %C (character).
The %X and %O options require a number of digits using the LFORMAT keyword,
you can specify to print a new line by including *N in your string.

Supported Operations:
<nowiki>
addition +
subtraction -
multiplication *
division /
modulo mod, M, m, or %
bitwise AND &
bitwise OR |
bitwise NOT ~
left shift Ish, L, or |
right shift rsh, R, or r
negation -
exclusive OR xor, X, or x
bitwise eqv, E, or e
equivalence

Example: SYS:> EVAL 0x5f / 010 LFORMAT="The answer is %X4*N"
The answer is 000B
