Thanks to all of you for the interesting suggestions
This is the compiler we use
PGM=CCNDRVR,PARM=('/SSCOM,LIS,LO,RENT,DLL,LP64,XPLINK')
We tried to use PARAM=(R1) but it doesn't work. Nothing passed in argv in the C
program
We also tried to add what suggested by David
If you want to pass the address of a parameter list in R1 use the following.
#pragma runopts(plist(os))
And in main
struct plist * parms = ( struct plist * ) __R1;
But we got
pragma runopts syntax (CEE3611): The run-time option PLIST was an invalid
run-time option or is not supported in this release of Language Environment.

Oggetto: Re: Assembler program attaching a C program
If this is a C program running under the LE enclave, then I would expect the
normal calling conventions to be used.
Wouldn't it be best practice to use standard OS conventions at least to the
main() function?
More questions, is this a main() function you are trying to attach or another
function?
Calling conventions are not the same.
Take a look at <https://publibz.boulder.ibm.com/epubs/pdf/cee14200.pdf>

BTW is the assembler program in an LE enclave?
