1These patches and supplemental programs should allow porting to MVS or MVS/XA
2in an EBCDIC envrionment, using SAS C V4.00C.

11The file "diffs" contains context diffs for changes to flex 2.3.
12
13The file "fixit.l" contains flex sources for a program to shorten external
14variable and function names to 8 characters or less. This is required for the
15"dumb" compiler linker used.
16
17The file "unfixit.l" reverses the changes in "fixit.l", to restore long names.
18This is useful when trying to build diff files as created here.
19
20The file "initscan.mvs.c" is an already "flexed" version of scan.l, in an
21EBCDIC environment.
22
23To install in an MVS environment, use patch to apply the diffs to flex 2.3,
24then run "fixit" on all .c, .h, .l, .y, and .skel files. Move the files
25to the MVS machine, and compile each of the .c files. (You will need a
26"yacc" functional equivalent under MVS to expand parse.y in that
27environment.) Link together, and the resulting flex should be ready to
28go. To test, run the MVSflex -is8 -Ce on the scan.l, and you should get
29back a file which is identical to initscan.mvs.c.

31Enjoy.
