Parameter list for the compiler interface initialization routine

In register 1, TSO/E REXX passes the address of a parameter list,which consists of a list of addresses. Each address in the parameter list points to a parameter. TSO/E REXX passes all parameters on the call. The high-order bit of the last address in the parameter list is set to 1. Table 1 lists the parameters for the compiler interface initialization routine.

Table 1. Parameter list for the compiler interface initialization routine
Parameter	Number of bytes	Description
Parameter 1	4	Environment block address. On entry, this parameter contains the address of the REXX environment block with which the compiler programming table is associated. This parameter is identical to the address in register 0. For more information on the REXX environment block, see .
Parameter 2	4	compiler runtime processor entry address. Specifies the address of the entry in the compiler programming table for the compiler runtime processor.
Parameter 3	4	compiler interface initialization routine return code. On exit, the compiler interface initialization routine must set this parameter to a return code that indicates the completion status of the compiler interface initialization routine. Table 1 lists the return codes for the compiler interface initialization routine.
