Good point Robert. SVC109 is for Type 3, 116 for type 1, 122 for type 2,
137 for type 6.
I always thought that there was another SVC table pointed to by the SVC
table entries for SVC 109, 116 etc., but can't see any hard evidence in
the Data Areas manuals. There is a cryptic reference to an ESR table
entry at offset 6 of SVCTABLE, but I can't make much sense out of it.

What you need is to look at the SVC Table which has an entry for
every SVC (used or not). It's documented under SVCTABLE in the MVS
Data Areas. The control block chain is CVT (CVTABEND) -> SCVT
(SCVTSVCT) -> SVCTABLE
This gets the standard SVCs (0-255) but does not get the extended SVCs
(IGXxxxxx) ones that are accessed via calls to a routing SVC (I forget
the 3 SVC numbers that provide this support).
