Question 1

I develop a vendor product that performs date simulation for applications that acquire the system date. This process currently works for applications that use the TIME macro (SVC 11) to get the date, but Language Environment (in some cases) does not use the TIME macro to get the system date, so which module and instruction do I need to zap in order to make my product work?

Answer:

You need to edit load module, CEEPLPKA, object module, CEEYGMT.

The instruction that needs to be zapped can be found at the following offsets in CEEYGMT:

OS/390 Rel	LE Rel	Base Offset	With PQ07708 Applied Offset
1.1	1.5	x'60'	x'88'
1.2	1.6	x'60'	x'80'
1.3	1.7	x'60'	x'80'
2.4/2.5	1.8	x'60'	x'80'
2.6	1.9	x'BC'
2.7	2.7	x'BC'
