DSA(name4 | (Rn|*)
returns the head of the chain of dynamic storage used by application programs
to make them reentrant (for example, for assembler programs, the DFHEISTG
storage).
name4
The name of a 4-byte area that is to receive the address of the head of
the dynamic storage chain.
(Rn) A register that is to receive the DSA address.
* The parameter list itself, in name APIQ_DSA, is used to hold the
address.
EIB(name4 | (Rn) | *)
returns the address of the EXEC interface block (EIB) for the current task.
name4
The name of a fullword area that is to receive the address of the EIB.
(Rn) A register that is to receive the address of the EIB.
* The parameter list itself, in name APIQ_EIB, is used to hold the
address.
RSA(name4 | (Rn|*)
returns the address of the register save area for the current task.
name4
The name of a fullword area that is to receive the address of the
register save area.
(Rn) A register that is to receive the address of the register save area.
* The parameter list itself, name APIQ_RSA, is used to hold the address.
