These patches and supplemental programs should allow porting to MVS or MVS/XA
in an EBCDIC envrionment, using SAS C V4.00C.

Included are:
        -rw-r--r--   1 swl26    1573 Jul 17 14:32 README
	-rw-rw-r--   1 swl26   20861 Jul 17 13:41 diffs
	-rw-rw-r--   1 swl26    5022 Jul 17 14:00 fixit.l
	-rw-rw-r--   1 swl26   97644 Jul 17 13:42 initscan.mvs.c
	-rw-rw-r--   1 swl26    4898 Jul 17 14:08 unfixit.l

The file "diffs" contains context diffs for changes to flex 2.3.

The file "fixit.l" contains flex sources for a program to shorten external
variable and function names to 8 characters or less.  This is required for the
"dumb" compiler linker used.

The file "unfixit.l" reverses the changes in "fixit.l", to restore long names.
This is useful when trying to build diff files as created here.

The file "initscan.mvs.c" is an already "flexed" version of scan.l, in an
EBCDIC environment.

To install in an MVS environment, use patch to apply the diffs to flex 2.3,
then run "fixit" on all .c, .h, .l, .y, and .skel files.  Move the files
to the MVS machine, and compile each of the .c files. (You will need a
"yacc" functional equivalent under MVS to expand parse.y in that
environment.)  Link together, and the resulting flex should be ready to
go.  To test, run the MVSflex -is8 -Ce on the scan.l, and you should get
back a file which is identical to initscan.mvs.c.

Enjoy.
