Not what you asked, but can one MVCL a load module from one address to
another and rely on its executing correctly? What about relocatable address
constants? (Less necessary today than once upon a time due to LARL, but
still lots of them around.) Of course in some case one might know that the
load module in question was a table e.g. that had no RLDs.

Subject: Load Library Module Length and Load Macro Module Length different
Values

Hi

 

I have a number of programs I am trying to move to CSA towards this end I
need to know the starting address and length of the load module 

 

Here is the code I use to obtain the length as register 1 low order 3 bytes
has the length in double words

 

SLL  R1,8   Get Rid of auth code

SLL  R1,5    Length is value times 8

 

 

After doing the following the result is X'000040000'  However looking in
ISPF browse for the loadlibrary in the size column it says X'3530' 

 

When I try to MVCL fore X'4000' I get s0c4 for X'3530' its okay
