The IBM OS/360 Fortran compilers allow $ as a letter. It comes after Z
such that one can
IMPLICIT INTEGER (A-$)
I believe the VMS compilers do also, as many VMS routines callable
from Fortran have $ in their names.
Note that the OS/360 compilers don't use call by reference for
scalar variables, but call by value result. That is, copy-in
and copy-out.
VAX/VMS has %val, %ref, and %descr such that one can override
the default convention for each argument.
