Message Switching Global Entries

Those message switching entries needed to define the configuration used by the customer reside in the Global area.

Following is a list of all message switching global entries, the value to which they are initialized and an explanation. Expansion should be included to reduce the amount of work to regenerate values.

@XIPLG DC X Switch for input log or not

X'00'
for no input logging

X'FF'
if input logging desired
@XIPCT DC H Number of terminals not assigned to input log
@XSATS DC H'7' Number of entries per XSAT record.
@XTATS DC H'10' Number of entries per XZ1AT record.
@XSYST DC X Type of System

X'00'
PARS only

X'80'
MS only

X'01'
PARS and low-speed MS

X'02'
PARS and high-speed MS

X'03'
PARS and mixed (low and high-speed) MS
@XSYTC DC H Number of entries in XR1TR (One plus the number of high-speed MS terminals).
@XSYLC DC H Number of MS lines per system (Sum of high-speed MS lines).
@XMXML DC H Maximum number of segments (381 byte blocks) per MS message.
@XMXRT DC H Maximum time range for a retrieval request before it is sent to CCS for approval.
@XMXRC DC H Maximum number of messages to be retrieved before being sent to CCS for approval.
@XKIND DC X'00' Message switching switch (used by MS programs and Recoup).
@X1SDL DC H Number of entries per XD0LS record. (Value derived from 360 divided by the rounded up @XSYTC) 8
@XMAVS DC H Mask for AVS/ASC should correspond to XTRT ordinal number for AVS/ASC line.
@XNHST DC H Number of high-speed terminal entries in XIST. (XICT should correspond).

The following two fields require field reservation in the global area, however, they are both initialized by the MS Restart Program.

@XIRPT DC F Retrieval Table (UV1RP) file address.
@XJRPT DC F Purge Table (UV3RP) file address.
