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-rw-r-- 1 swl26 20861 Jul 17 13:41 diffs

-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.
