Invoking APPC/VM Communication Functions
VM programs at each end of an APPC/VM path use APPC/VM functions
to communicate with each other. Most APPC/VM communications functions
are provided as parameters of the APPCVM macro. The APPC/VM communications
functions used with the APPCVM macro are:
- CONNECT
- RECEIVE
- SENDCNF
- SENDCNFD
- SENDDATA
- SENDERR
- SENDREQ
- SEVER.
In addition, some APPC/VM functions are provided as parameters
on the IUCV macro. The APPC/VM communications functions used with
the IUCV macro are:
- ACCEPT
- QUERY
- SEVER.
The IUCV macro
functions relate to both APPC/VM and
IUCV paths. The IUCV functions are not defined by the SNA LU 6.2 (APPC
architecture) verb interface, but they are a necessary complement
for APPC programs executing in a VM processor. The IUCV macro functions
that relate to APPC/VM are:
- ACCEPT
- CONNECT
- DCLBRF
- DESCRIBE
- QUERY
- RTRVBFR
- SETCMASK
- SETMASK
- SEVER
- TESTCMPL
- TESTMSG.
Note: Other IUCV macro functions are possible from APPC/VM,
but are not recommended for use by APPC/VM programs running in CMS.
See How APPC/VM Relates to General IUCV for more information about these other IUCV
functions.
