There are (2) Rexx execs located on file 220 of the CBTtape.org web site (V492) (http://www.cbttape.org/ They are LISTSVCJ and LISTSVCT. These execs will list the SVC Update Journal table and the all of the active SVCs respectively.

The routines for SVC types 3 and 4 are named IGC00xxx, where xxx is the SVC number. If a type 4 SVC routine calls for multiple SVC loads, the naming convention is to identify each load by increasing 00 by one. For example, IGC03xxx indicates the third module loaded within a type 4 SVC routine. For types 3 and 4 SVC routines, the internal format of the SVC number (xxx) is zoned decimal with a four-bit sign code (1100) in the four high-order bits of the low order byte. Any low-order digit in a type 3 or 4 SVC number that is between 1 and 9 will be an EBCDIC character between A and I in the load module name. For example, the load module name for SVC 51 (X'33') would be IGC0005A because the low order byte is 1100 0001, or A in zoned decimal. A low-order zero in the SVC number corresponds to a hexadecimal C0 in the load module name. ESR type 3 routines have names in the format IGX00nnn, where nnn is the decimal code placed in register 15 when SVC 109 is issued From this you can see what the convention is for naming an SVC. Depending on what SVC you are looking for (TYPE1/2/3/4/6 or a Router), you would look for the name. If you have a tool like MXI, SHOWMVS, Omeagmon, Sysview, SAS, etc... You can scan the system either live or after the fact. If you try ISRDDN and use the LPA command then search for the module name you can see if it is in a library. you might try searching the internet and see if anyone created REXX code to go through control blocks to display SVCs.
