COND Class
Parameter: Boolean expressions.
Optional modifiers: TRUE, FALSE, PREF, SUF, NULL.
Algorithm:
If the condition is true, processes the rule specified by TRUE; otherwise processes
the rule specified by FALSE.
If the result string is empty, processes the rule specified by NULL, and returns the
NULL result; otherwise processes the rule specified by PREF and inscribes the PREF
result as a prefix for the result string; then processes the rule specified by SUF and
inscribes the SUF result as a suffix for the result string.
Example
create COND BOOLEAN (uppercase)
TRUE=CREATE
FALSE=create;
where uppercase is a Boolean variable.
