I can't tell for certain, but this sounds like a known defect in the
6.5 S300 FORTRAN compiler.  There is a patch that you can obtain from
your SE for this problem (if it is the one I think it is).

The problem occurs with statements like:

	write (99) (charvar(i),i=1,20)

where charvar is a character variable.  Try modifying the loop to read:

	write (99) (charvar(i+1),i=0,19)

You can verify approximately which line is causing the compiler to choke
by compiling with the -L (listing) flag turned on.
