Guardian Procedure Calls Reference Manual

• Note that since all DEFINEs are propagated to the backup process when it is created, use of
CHECKDEFINE is not necessary unless one or more DEFINEs are changed.
• If a call to CHECKDEFINE causes a DEFINE in the backup to be altered, deleted, or added,
then the context-change count for the backup process is incremented.
Example
STRING .EXT define^name[0:23];
LITERAL success = 0;
.
.
define^name ':=' ["=mydefine "];
status := CHECKDEFINE ( define^name );
IF status <> success THEN ... ;
