Select "old" list-directed output style.
SPARC:77 x86:77
Omit the blank that starts each record for list-directed output. This is a change from f77 releases 1.4 and earlier. The default behavior is to provide that blank, since the Fortran Standard requires it. Note also the FORM='PRINT' option of OPEN. You can compile parts of a program with -oldldo and other parts without it.
