The objective here is to get all the .src, .obj, .com, and the .pt and .ot and other files, so that all source, object, and absolute files are represented on the website under XPL.

9/19/18
Created a copy of all the file structure above under a ROOT directory in the current REOPEN directory.  From within this directory, I did a MAKE$ to make another XPL identical to the current working XPL.

9/22/18
Moved into XPMode ROOT, did a DIR /S >DIR.TXT, and XCOPYed that file into this directory.  This text is inserted below and will be edited into the index.html for each subdirectory in Legacy\XPL.  But first, I deleted the extraneous .bat files from the subdirectories, and I added a web.bat to each directory to direct the XCOPY of files from there to here (deleted from the website directories, however).

The total (edited) list of (130) files is:

Now, each of these subdirectories must be visited so that any .obj and .com files can be converted to .txt files using DUMP.  The current Legacy\XPL\ [DEXPL, LINK, XPL] directories can be deleted.  When web.bat is executed from the various directories on the XPMode side, the Legacy\XPL\ [DEXL, LINK, PRINT, XPL, XREF] directories will replace them.

root->XPL (.bat files; deleted web.bat in Legacy target)
root\dexpl->XPL\DEXPL (.ot, .pt, .bat, .src; deleted web.bat)
root\dexpl\com->XPL\DEXPL\COM (.txt; after DUMP & EDIT of each .obj & .com)
root\dexpl\otran->XPL\DEXPL\OTRAN (.ot, .pt, .bat, .src; deleted web.bat)
root\dexpl\otran\com->XPL\DEXPL\OTRAN\COM  (.txt; after DUMP & EDIT of each .obj & .com)
root\dexpl\ptran->XPL\DEXPL\PTRAN (.ot, .pt, .bat, .src; deleted web.bat)
root\dexpl\ptran\com->XPL\DEXPL\PTRAN\COM  (.txt; after DUMP & EDIT of each .obj & .com)

9/23/18
Upgraded DUMP so that post-DUMP edit is no longer necessary.  Resume directory traverse.
root\link->XPL\LINK (.src, .bat; deleted web.bat in target)
root\link\com->XPL\LINK\COM (.txt; after DUMP of each .obj & .com)
root\print->XPL\PRINT (.src, .bat; deleted web.bat in target)
root\print\com->XPL\PRINT\COM (.txt; after DUMP of each .obj & .com)

root\xpl\com->XPL\XPL\COM (.txt, .def; after DUMP of each .obj & .com)
root\xref->XPL\XREF (.bat, .src; deleted web.bat in target)
root\xref\com->XPL\XREF\COM (.txt; after DUMP of each .obj & .com)
File migration complete.  Now, proper index.html files have to be linked to the text files, and all the .ot, .pt, .bat, .def, and .src files have to be renamed with .txt suffixes.

Renaming complete.  Snips of the DIR /S (above) will now be copied into the index.html files and the links to the files will be fixed.  Another (final?) directory traversal.

Traversal is now at the LINK subdirectory, with PRINT, XPL, and XREF left to go.

9/24/18
Opened LINK\index.html and proceeded to edit it.  Worked through the remainder of the directories.  Will now try to browse through the entire structure.  Success!
