How to extract OpenEdge source code from standard libraries

To extract all files from a Progress/Open Edge source code library:

1.  Launch proenv window
2.  cd %DLC%\src
3. extractpl <library file>

The files will be extracted to a directory under %DLC%\src with the same name as the library.

For example:

1. proenv
2. cd %DLC%\src
3. extractpl prodict.pl

To see the extracted files and directories:

1. cd prodict
2. dir /w

The output will look similar to this:

_dctadmn.p  _dctname.p  _dictc.p    dictvar.i   gui         ora
_dctalia.p  _dctquot.p  admnhlp.i   dump        load_d.p    pro
_dctcach.p  _dctscnt.p  as4         dump_d.p    load_df.p   rplctn
_dctexec.p  _dctsget.p  dictgate.i  dump_df.p   load_seq.p  send_sql.p
_dctexen.p  _dctsset.p  dictnext.i  dump_fd.p   misc        user
_dctgues.p  _dctsylk.p  dictsplt.i  fhidden.i   mss
_dctlrec.p  _dctyear.p  dictsrch.i  gate        odb

The example shows the files and directories extracted from prodict.pl in Progress 9.1x.  The contents of the source code libraries may vary in different Progress/OpenEdge releases.
