The enclosed disk contains patched versions of the FORTRAN version 5.0
compiler (F1.EXE) and high-capacity compiler (F1L.EXE). If you are not
currently using the high-capacity compiler, disregard F1L.EXE. Copy
F1.EXE and F1L.EXE into the directory that contains your FORTRAN
executable files (for example, C:\BIN). Consult the README.DOC file
from your original FORTRAN 5.0 Setup disk for information about using
the high-capacity compiler.

This application note provides corrections for the problems described
below:

1. Using an element of a STRUCTURE within an I/O statement inside a
subroutine, which generates a protection violation with OS/2 during
compilation, or the following compilation error with MS-DOS:

F1001: Internal Compiler Error, omf_ms.c:1.118, line 1093

2. NAMELIST statements in multiple subprograms in one file stopping
the machine

3. SAVEing a common block in multiple subprograms, which generates the
following compiler error:

F2348: already declared SAVE.

4. Using /4Yi, /4Ys, or /4Yv and an asterisk in column 1 to indicate a
comment, which generates the following compiler error:

F2037: illegal label field.

Both the patch and the original F1.EXE files are the same size. To
differentiate between the two, use the undocumented /4Yz switch as follows:

fl /4Yz .for

The filename must be an existing FORTRAN file. The new patched F1.EXE
will display:

.for
