SEQNUM - generate a fresh integer.

Usage:

$seqnum([integer expression])

Where:

integer expression: is an optional expression yielding an integer value.

Description:

For users who wish to generate labels, the SEQNUM macro provides a fresh integer value each time it is referenced. The value of the expression is added to the generated number before the result is substituted. Thus the same value may be generated twice by coding "$seqnum(1)" and "$seqnum()" successively.

Although the SEQNUM macro is intended for generating labels, the fact that Pascal demands labels be predeclared severely restricts its usefulness.
