It is possible to jump from Assembler to labelled Fortran statements and
vice-versa. As in the above example, labels are Fortran labels and are referred
to by preceding the numeric label by a dollar character thus:
Conditional jumps are coded in 32-bit form when necessary, so these may be used
without considerations of range. The LOOP instructions, which do not have
32-bit forms, are not supported by the assembler.
