Re: A curosity question about IHAETD macro

[Peter Relson]

I'm afraid that the curious will have to remain curious.

This is not part of the programming interface; no relevant further information 
is available or likely to be made available.
I'm sure you can figure out that the bit is set by the RECORD keyword of ETDEF. 
That is commented in the macro as "internal use only".

Nothing can stop a suitably authorized program from doing whatever it wants. So 
of course a program "can" set the bit. It is expected not to do so. It would be 
taking its own risk and imposing risk on the entire system in doing so.

A curosity question about IHAETD macro

[esst...@juno.com]

Hello -.A curiosity question about IHAETD macro of SYS1.MACLIB.
.
ETDHFLAG DS B All non-used bits must be zero. @
ETDRCRD  EQU X'80' If bit is ON, NO recording of cross @
* memory connections will be performed. 
* If bit is OFF, recording will be done.
* Classification: DMTI 
.
There is a field ETDHFLAG with an equate ETDRCRD in IHAETD.
The comment states: if the bit is ON, no recording of
cross memory connections will be performed -
.
How is this bit set OFF/ON ?
When is this bit set OFF/ON ?
What determines when this bit is turned OFF/ON ?
Where is the data written to/stored? 
What information is collected ?
Can an authorized user program set this Flag before
the ETCRE macro is issued ?
.
Is there any additional documentation on this field other
than the macro itself ? 
.
Curious minds want to know.paul..
