Lindy, From "A Guide to Using MVS/XA Interface Facilities" an SRA tutorial from the Jurassic age:
"The type 5 SVC facility permits a user to indicate (at system generation time) that one or more user-written SVC routines are going to be added to the system after the completion of system generation..... If a type 5 SVC is specified at system generation time, the resulting entry in the SVC table points to the entry point address of IGCRETRN.... " You could define the characteristics of the SVC etc. without having the code availble during SYSGEN. This was an ancient way to save space in the SVC table. Cheers, Jon Jon L.

I'm just curious because the numbers for SVC types go from 1 to 6 with 5 left out. Is there such a thing, or was there such a thing as a type-5 SVC?
