*
* Revision 3.94 1994/07/07 01:51:49 lindner
* Fix bug
*
* Revision 3.93 1994/07/06 15:36:27 lindner
* These changes are from F. Macrides:
*
* Moved declaration and initialization of setlocale_LangDir to
* globals.h.
*
* Note that setlocale() doesn't yet work with VMS Alphas, so it
* presently just returns without doing anything and the "hardcoded"
* English text is used. It all works fine with VAXen.
*
* Added code to delete the temporary file when gopher is called with the
* -p or the new -u switch.
*
* Added J. Lance Wilkinson's (JLW@psulias.psu.edu) internationalization
* port to VMS and: 'L' operation for changing language on the fly.
*
* Pause after telnet/tn3270 to permit reading of any error messages.
* Added telnet and tn3270 to prompt for a URL via the 'w' command.
*
* Modified Alan's dialog box title and prompt for the 'w' command.
*
* NEVERSETOPTIONS compilation symbol disables ability to set options via
* SetOptions() and issues an appropriate message.
*
* NEVERSPAWN compilation symbol disables the spawn command and issues an
* appropriate message.
*
* On VMS, the NEVERSETOPTIONS and NEVERSPAWN symbols can be used to
* create a gopher image for CAPTIVE accounts which still permits
* functions that would be disabled by the -s or -S switch, but issues an
* appropriate message (rather than a DCL error message) on spawn attempt
* and precludes "creative" modifications of the display software and
* print command mappings.
*
* Added missing ! for NoShellMode under binary and and encoded save to
* disk if().
