Examples
Example 1: Program section as curve table definition
A program section is to be used unchanged for defining a curve table. The
STOPRE command
for preprocessing stop can remain and is reactivated immediately as soon as the program
section is no longer being used for table definition and
CTABDEF and CTABEND have been
removed.
