COBOL
Figure 41 on page 531, in COBOL, redefines the NETNAME, so that the last four
characters are used to select a more suitable model than that selected in the
sample control program.
* R7 now points to model name
VALIDT CLI SELECTED_MODELNAME,C’ ’ MTS model name supplied?
BNE VALIDM1 Yes
LH R6,MODELNAME_COUNT Count of models
LTR R6,R6 Were any presented?
BZ RETURN No
LA R8,MODELNAME First model name
*
LOOP2
CLC 8(8,R7),0(R8) Is this model name here?
BE VALIDM
*
LA R8,L’MODELNAME(R8) Next model name
BCT R6,LOOP2
*
*
Now we know the required model name was not presented
* to this exit by CICS, a return rejects the logon
*
B RETURN
*
*
At this point the model name was found in those presented
* It is given to CICS and the new termid is
* the netname
*
VALIDM
MVC SELECTED_MODELNAME,0(R8) R8 was left pointing at
* model name
VALIDM1 DS 0H
MVC SELECTED_TERM_ID,NETNAME Use netname for termid
* (4 chars)
*
*
* SELECTIONS COMPLETE, RETURN
*
MVI SELECTED_RETURN_CODE,X’00’ Indicate all OK
B RETURN Exit program
*
*
Table of netnames allowed to log on and the model name
* necessary for the logon to be successful
*
*
Format of table :
* Bytes 1 to 8 Netname allowed to log on
* 9 to 16 Model required for netname
*
DS 0D
TABLE DC CL8’L77A’,CL8’3270064’
DC CL8’L77B’,CL8’3270065’
TABLEN DC Y((*-TABLE)/16)
