Subject: Off topic question about shebang and exec()

Hi all

I apologize for abusing the knowledge of the people on this list, but I
know they will know the answer. Google does not provide a usable answer.

I am busy writing a toy language and I would like it to be used as both a
compiler and "interpreter"

I would like it to compile the source and then run the resulting binary
when the source file is called via the shebang and it should just do a
normal compile when called with "compile code.src"

argv[0] contains the path to the compiler in both cases, which makes sense.

Is there any way to determine which method was used to call the compiler?

Kind Regards
Paul
