I would absolutely love to see someone code the TEXT-UNITS for a DYNALLOC without using coded example and see how many days it would take them

The simplest code for a Br14 is

        LA       R15,0
                BR       14

It is a 2 instruction program that is as simple as it gets

I think that LA is actually a XR 15,15 or a SR 15,15.

Note that the zero'ing of 15 was one of the 2 mentioned APARs. The original version did not clear 15 before returning via 14. I forget what the other APAR was for.

I have not been following this thread -- seemed like IBMMAIN
navel-gazing -- but FWIW IEFBR14 seems to be documented in the JCL U/G.

I like to maintain the distinction between a Guide and a Reference. 
The Guide describes techniques; the Reference specifies functions.

Are you saying that it isn't documented if it is only documented in a User's Guide?

If that is the case, you'll never be able to use DYNALLOC.
