Evaluates an expression. (NM)
CALC expression
expression The expression to be evaluated.
The CALC command evaluates an expression and displays the
result to $STDLIST. Expressions can yield integer, string,
or boolean results. Integer results are displayed in
decimal, hexadecimal ($ prefix), and octal (% prefix)
notations. Boolean expressions are displayed as TRUE or
FALSE. The variable HPRESULT is set to the result of the
last expression evaluated by CALC. HPRESULT's type
changes, depending on the type of result generated by CALC.
Do not use the FINFO function with CALC to get information on
remote files. FINFO ignores them and returns incorrect
information.
The operands allowed in an expression are: any variable, integer,
string, or Boolean constants, and the system-reserved words WARN,
FATAL, SYSTEM, OK. Compound logical expressions can be formed
using the AND, NOT, XOR, and OR logical operators, optionally
nested within parentheses.

at the HELP prompt. Or, you may enter an individual variable
name for more specific information.
This command is available in a session, job, program, or in
break. Pressing [BREAK] terminates the INPUT() function.
The result of CALC EXPRESSN depends on the value entered
for EXPRESSN and on the type of the value:
