At the beginning of the NCK-SPL (standard cycle SAFE.SPF), freely selectable
names are assigned to system variables $A_INSE/$A_OUTSE and $A_INSI/
$A_OUTSI using the "DEFINE" instruction. This makes the program easier to
read and facilitates making changes to the terminal assignment.
The "DEFINE" statements must be placed at the beginning of the NCK-SPL. In
the tabular list, names used in the example program are listed in the column
headed "Symbolic".
