Your on lp64, is the invoking program passing a 64 bit address. main() is
slightly tricky but the second word or dword in param list pointed to by R1
should point to sequence of address which point to null terminated strings.

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?
