Preparing SCREEN
COBOL Object
Libraries
A TRANSFER configuration includes SCREEN COBOL object libraries provided by
Tandem with TRANSFER software and can also include user-written SCREEN
COBOL object libraries.
The libraries provided by Tandem reside on your user-DSVs and are available to the
installation procedures. The installation procedures by default assign the libraries to
TCPs. The libraries and the TCPs to which the libraries are assigned are:
TRAN—configured for TRAN-TCPs with the Base TRANSFER component
This library contains the ADMIN program, with which you configure agents, and
the TMANAGER program.
TAREQ—configured for TAREQ-TCPs with the Base TRANSFER component
M6530—configured for M6530-TCPs with the PS MAIL 6530 client
M3270—configured for M3270-TCPs with the PS MAIL 3270 client
Preparing User-Written
Object Libraries
If you have user-written SCREEN COBOL clients, agents, or extensions, you must
provide them in a SCREEN COBOL object library before defining the TRANSFER
component that requires the library.
You might want to separate user-written libraries and libraries supplied by
TRANSFER. Although keeping SCREEN COBOL libraries separate does cause a slight
degradation of performance, it greatly simplifies your work when you want to update
your libraries. When you receive a new version of TRANSFER libraries, you can
install them without sorting through your existing libraries. To keep the libraries
apart, do the following:
Configure the libraries supplied by Tandem for TCPs.
Configure user-written libraries for terminals or programs.
Do not put object code supplied by Tandem in user-written libraries.
Do not put user-written object code in object libraries M6530, M3270, TAREQ, or
TRAN.
The installation procedures fulfill the first two conditions; you can fulfill the last two
when you prepare user-written libraries.
Note If you have a user-written extension for M6530 and that extension invokes ADMIN or TMANAGER, you
cannot follow the last two suggestions because you need three SCREEN COBOL libraries (TRAN,
M6530, and CUST), but only two can be configured. In this case, you must put your modules in a
Tandem library or put Tandem modules in a user-written library.
