UPDATE# NEW SCRIPT PROGRAMMING COMMANDS AND FEATURES

IF [ NOT ] EXIST <filename>
  Succeeds if the given file exists, fails otherwise.

IF [ NOT ] INPATH <filename>
  Succeeds if the given file can be found by normal DOS search rules,
  i.e. if it is in the current disk/directory, or in the DOS PATH.

INCREMENT <variable> [ <value> ]
  Adds the <value>, which must be a positive number (or a variable that
  evaluates to a positive number), to the value of the given variable.	If the
  <value> is not specified, then 1 is added.  If the <variable> is not defined
  or has a non numeric value, the command fails and the value of the variable
  is not altered.

DECREMENT <variablename> [ <value> ]
  Subtracts the <value>, which must be a positive number (or a variable that
  evaluates to a positive number), from the value of the given variable.  If
  the <value> is not specified, then 1 is subtracted.  If the <variable> is
  not defined or has a non numeric value, the command fails and the value of
  the variable is not altered.

STOP [ <number> [ <text> ] ]
  Stops execution of the current macro or TAKE file and returns immediately
  to top command level.	  The <number> and <text> operands are new.  <number>
  is a return code that can be tested by IF SUCCESS.  It is also assigned to
  \v(status).  Text is an optional message to be printed.

END [ <number> [ <text> ] ]
  Stops execution of the current macro or TAKE file and returns immediately to
  the level which invoked it, i.e. the next higher level.  <number> and <text>
  are used as in the STOP command.  POP is a synonym for END.

\L in an OUTPUT string sends a Long (1.5 second) BREAK.	 On a network
connection, it sends the same thing that \B (regular BREAK) would send, such
as a TELNET BREAK command.

New variables:

  \v(dosversion) - MS-DOS version, e.g. 500 for DOS 5.00.
  \v(line)	 - Current SET PORT value: COM1, COM2, TCP/IP, etc.
  \v(ntime)	 - Numeric representation of current clock time: hhmmss
  \v(port)	 - Same as \v(line)
  \v(session)	 - Current TCP/IP session number
  \v(terminal)	 - Current terminal emulation type

Note: \v(ndate) and \v(ntime) are suitable for construction of filenames.
