Note that in the C zsysc file, the type zsys_ddl_char_extaddr_def is defined as long. The

type char_far* is the equivalent to the type zsys_ddl_char_extaddr_def in DLAUNCHH.

Therefore, do not use the structure definition from zsysc and the default structure value from

DLAUNCHH at the same time.

C programs must initialize the P_L_DEFAULT_PARMS_ define in the $SYSTEM.SYSTEM.DLAUNCHH

header file.

In the C zsysc file, the structure for the param-list parameter is defined as:

#pragma fieldalign shared2 __zsys_ddl_plaunch_parms64

typedef struct __zsys_ddl_plaunch_parms64

{

short z_version;

short z_length;

short z_priority;

short z_cpu;

long long z_nowait_tag;

long long z_mainstack_max;

long long z_heap_max;

long long z_space_guarantee;

zsys_ddl_char_ext64addr_def z_program_name;

zsys_ddl_char_ext64addr_def z_library_name;

zsys_ddl_char_ext64addr_def z_swapfile_name;

zsys_ddl_char_ext64addr_def z_extswapfile_name;

zsys_ddl_char_ext64addr_def z_process_name;

zsys_ddl_char_ext64addr_def z_hometerm_name;

zsys_ddl_char_ext64addr_def z_defines_name;

__int32_t z_program_name_len;

__int32_t z_library_name_len;

__int32_t z_swapfile_name_len;

__int32_t z_extswapfile_name_len;

__int32_t z_process_name_len;

__int32_t z_hometerm_name_len;

__int32_t z_defines_name_len;

__int32_t z_pfs_size;

__int32_t z_create_options;

short z_name_options;

short z_debug_options;

short z_memory_pages;

short z_jobid;

__int32_t z_filler1;

} zsys_ddl_plaunch_parms64_def;

Note that in the C zsysc file, the type zsys_ddl_char_ext64addr_def is defined as long

long. The type char _ptr64 * is the equivalent to the type zsys_ddl_char_ext64addr_def

in DLAUNCHH. Therefore, do not use the structure definition from zsysc and the default structure

value from DLAUNCHH at the same time.

C programs must initialize this structure with the P_L_DEFAULT_PARMS_ define from the

$SYSTEM.SYSTEM.DLAUNCHH header file.

Z^VERSION

identifies the version of the ZSYS^DDL^PLAUNCH^PARMS structure.

This table summarizes the possible values for Z^VERSION. TAL literals are defined in the

ZSYSTAL file. Literals in the zsysc file, for C programs, are the same as those for TAL except

that they contain the underscore (_) character instead of the circumflex (^) character.

This value must be supplied:

DescriptionValueName (ZSYS^VAL^ )

The current version of the 32-bit structure1PLAUNCH^PARMS^VER

The current version of the 64-bit structure2PLAUNCH^PARMS64^VER
