Online System Overview 

All transaction points to AROXCTL Programs and Transactions are defined in AROPGM1



File names are defined in AROFIL1



All transactions trigger AROXCTL



AROXCTL will transfer control to corresponding program using AROPGM1



Use AR60PD & AR70PD Copybooks for MAP handling

Programs & Copybooks 



 



Each subsystem has it’s own COMMAREA Generic details, such as Date, Region Name, Access Routine names etc will be stored in COMMAREA AROXCTL builds COMMAREA COMMAREA can be used to data between programs. Example File Key COMMAREA  AR60WS – CMS  OF60WS – FAS  OC60LK – CTA  LT60WS – LTS

Programs & Copybooks Cont.. 

Programs does not contain native CICS commands



Use AR60PD & AR70PD to perform SEND MAP, RECEIVE MAP, XCTL, LINK etc



Use File Access Routines for file handling



Screen Number Ranges from 00 to 49 Pressing enter on 01 Screen will control to Second screen After Successful edit, Perform AR60PD-EDIT-PAGE-NBR to edit the Screen number If the enters screen number, then the corresponding screen will be displayed If the enters Invalid Screen Number (NBR > MAX Screen NBR) then Last Screen will be displayed If the enters Non Numeric Value, next screen will be displayed
