From TSO, each user executes the MSOUSER CLIST (provided by the MSO installer) to be used for the MSO region desired. This CLIST calls the MSUSER module that connects a user to the MSO region.
The following sample MSO CLIST is provided in MSO.DATA(MSOUSER).
ALLOC F(FOCLIB) DA('prefix.FOCLIB.LOAD') SHR REU
ALLOC F(USERLIB) DA('prefix.FOCLIB.LOAD') SHR REU
ALLOC F(ERRORS) DA('prefix.ERRORS.DATA') SHR REU
ALLOC F(MSGET) DA('prefix.MSO.MSGET') SHR REU
ALLOC F(MSPUT) DA('prefix.MSO.MSPUT') SHR REU
ALLOC F(MSOPRINT) DA(*)
CALL 'prefix.FOCLIB.LOAD(MSUSER)'
After a few seconds, the FOCUS Terminal Operator Environment screen appears and the user may begin using FOCUS.
We recommend that CICS sites test the installation of MSO using TSO if possible, before testing access from CICS.
