The authorized assembler services guide describes the registers on entry to an SRB routine.
The documentation that describes the setting of R2 currently mentions the FRR parm (as that is what the parm was when only the SCHEDULE macro was involved). With the advent (long ago, now) of IEAMSCHD, that becomes incomplete and should mention the FRRAD parm when IEAMSCHD is used. I also noticed that the description of reg 1 on entry to the SRB routine was somewhat unclear, so will get that clarified. Reg 1 will contain the value of SRBPARM (when SCHEDULE is used) or the value provided by PARM= (when IEAMSCHD is used) We will get the documentation updated.
