CELQPIPI(init_main) — initialize for main routines

The invocation of this routine:

Creates and initializes a new common run-time environment (process) that allows the execution of main routines multiple times
Sets the environment dormant so that exceptions are percolated out of it
Returns a token identifying the environment to the caller
Returns a code in Register 15 indicating whether an environment was successfully initialized


Syntax

>>-CALL--CELQPIPI--(--init_main--,--ceexptbl_addr--,------------>

>--service_rtns--,--token--)-----------------------------------><

init_main (input): A fullword function code (integer value = 1) containing the init_main request.
ceexptbl_addr (input): A doubleword containing the address of the PreInit table to be used during initialization of the new environment. Language Environment does not alter the user-supplied copy of the table. If an entry address is zero and the entry name is non-blank, Language Environment searches for the routine and dynamically loads it. Language Environment places the entry address in the corresponding slot of a Language Environment-maintained table.
service_rtns (input): A 64-bit pointer containing the address of the service routine vector or 0, if there is no service routine vector. See Service routines for more information.
token (output): A doubleword containing a unique value used to represent the environment.
The token should be used only as input to additional calls to CELQPIPI, and should not be altered or used in any other manner.
