target language type (was API parameter lengths)

[Gene_Gaunt@xxxxxxxxxxxxxxx]

Thanks Leif, the associated space information is useful.

I I think I answered my own question.  I just found some old notes that I
think show how the system knows the target program language type.  Run the
MI code below to get the language type into field "LANGUAGE".  You'll first
have to resolve the system pointer "?POINTER" to some ILE program that has
a PEP.

If the target program is ILE RPG, the language type will be X"00170002".
If the target program is ILE C, the language type will be X"00050000".
Hmm, maybe this is how the ILE debugger determines which debugging commands
"flavor" to allow.  I tried playing with language types other than
X"0170002" and X"00050000", and the ILE debugger said such a program can't
be debugged!

DCL SYSPTR ?PROGRAM   AUTO;
DCL DD     LANGUAGE   AUTO CHAR(4);

DCL SPCPTR ?TEMPLATE  AUTO INIT(TEMPLATE);
DCL DD     TEMPLATE   AUTO CHAR(48) BDRY(16);
DCL DD     *          DEF(TEMPLATE) POS(1) BIN(4) INIT(48);
DCL DD     *          DEF(TEMPLATE) POS(9) BIN(4) INIT(1);
DCL SPCPTR *          DEF(TEMPLATE) POS(17) INIT(RECEIVER);
DCL DD     OPTIONS    DEF(TEMPLATE) POS(33) CHAR(8);
DCL DD     MODULENO   DEF(TEMPLATE) POS(41) CHAR(4);

DCL DD     RECEIVER    AUTO CHAR(512);
DCL DD     *           DEF(RECEIVER) POS(1) BIN(4) INIT(512);

CPYBLA     OPTIONS,   X"0000800000000000";
MATBPGM    ?TEMPLATE, ?PROGRAM;
CPYBLA     MODULENO,  RECEIVER(65:4);
CPYBLA     OPTIONS,   X"0000000080000000";
MATBPGM    ?TEMPLATE, ?PROGRAM;
CPYBLA     LANGUAGE,  RECEIVER(401:4);
BRK "LOOK";
