The DETAC macro or the detac or detac_ext (detach) functions allow you to temporarily detach the main storage block on a given ECB data level or DECB without releasing it. Use this facility if:
You must reattach the block with the same data level in that ECB using the ATTAC macro or the attac or attac_ext function.
Excessive use of the detac and attac functions can cause a depletion of working storage: you should carefully monitor their use.
