Hi All,
I am developing a new application that has a front end in dot net and book end uses rexx to do processing along with jcls.
to initiate the backend process from front end i am FTPing a jcl directly to internal reader that calls REXX module.
All this is working fine. But the hitch is:
The job that i FTP to initiate the complete backend process needs user's Accounting information. Although i am accepting the user's login id and password but wanted to know if there is any mode through which i can get the accounting information from mainframe on the basis of user id. |

*------------------------------------------------------------------*/
NUMERIC DIGITS(32)
TCB=STORAGE(D2X(540),4)
JSCB=STORAGE(D2X(C2D(TCB)+180),4)
SYSJESN=STORAGE(D2X(C2D(STORAGE(D2X(C2D(JSCB)+316),4))+12),8)
JCT=STORAGE(D2X(C2D(JSCB)+260),4)
SYSJOBN=STORAGE(D2X(C2D(JCT)+24),8)
ACT=STORAGE(D2X(C2D(JCT)+56),3)
SYSPGMR=STORAGE(D2X(C2D(ACT)+24),20)
ACTL=C2D(STORAGE(D2X(C2D(ACT)+48),1))
SYSACCT=STORAGE(D2X(C2D(ACT)+49),ACTL)
IF SYSVAR(SYSISPF)=ACTIVE
THEN ADDRESS ISPEXEC 'VPUT (SYSJESN SYSJOBN SYSPGMR SYSACCT) PROFILE'
ELSE SAY WORD(SYSJOBN,1)'('SYSJESN') ACCOUNT('SYSACCT')' SYSPGMR
EXIT

Start with learning the STORAGE function of REXX.
Then, read the relevant materials regarding MVS Data Areas.

Thanks a lot for the your code. it works perfectly fine.
I went through the description of "storage()" function and now have some understanding about it.
| Code: |
TCB=STORAGE(D2X(540),4)
|
What i am not able to understand is why do we start referencing to the memory from 540 = x'21c' to get the data related to accounting info. And where does this memory refer to?
Please provide some info on this. |

because the manuals say it 
You are not getting the accounting info from there,
You start chasing a chain of control blocks, which at the end take You to the control block containing the accounting info

it refer to absolute address 540 which is part of the PSA ( prefixed storage area )
and it points to the current TCB address
look at the ibm docs for the desription of the storage areas related to control blocks |
