Compiler generated self-modifying code:  YES.

When I was a graduate student (in ancient times:  1974) I had occasion to
look at the generated code for both a CDC 6000-series Fortran compiler and
an IBM 370-series COBOL compiler.  Both compilers used the same technique
for inserting argument addresses in subroutines (did you know COBOL has
subroutines?!!!).  The compilers generated code that copied the argument
addresses from the argument list into the instruction address fields.
