Making your IMS application reentrant

For many IMS™ users, the storage required at run time for any given IMS transaction can be fairly large. Therefore, the most efficient method of coding an application is to make it reentrant. This method can eliminate application loading time, speed up IMS initialization and restart, and provide the additional integrity that results from having your routines in protected storage.

Methods for making your application reentrant differ across HLLs. For more information, see Making your application reentrant.
