$! NetHack.Com -- sample command procedure for invoking NetHack  9-JAN-1993
$ v = 'f$verify(0)'
$!
$!    Possible command line arguments include
$!	"-uConan-B"	!play a barbarian named Conan
$!	"-u" "Merlin-W" !play a wizard named Merlin (slight variant of above)
$!	"-e" or "-E"	!play an elf with default name (from environment
$!			! [ie, NETHACKOPTIONS logical name] or VMS username)
$!	"-a" or "-A", "-b" or "-B", "-c" or "-C", ... !specify character type
$!			!note: "-s" is ambiguous between "play as a samurai"
$!			!   vs "show scoreboard", so use "-S" for the former
$!	"-x" or "-X"	!play in 'explore' mode (practice for beginners)
$!	"-D"		!play in 'wizard' mode (for debugging, available only
$!			! to the username compiled into nethack.exe as WIZARD)
$!	"-dec"		!turn on DECgraphics mode (VT100 line drawing, done
$!			! automatically below if appropriate term attribs set)
$!	"-d" dir-path	!specify an alternate playground directory (not
$!			! recommended; define HACKDIR instead)
$!

$!
$! assume this command procedure has been placed in the playground directory;
$!	 get its device:[directory]

$!
$! hackdir should point to the 'playground' directory

$!
$! termcap is a text file defining terminal capabilities and escape sequences
$ if f$trnlnm("TERMCAP").eqs."" then  define termcap hackdir:termcap
