Options beginning with a slash (/) are called
switches. A "switch" is a means used to
specify parameters.
is a string literal (not included in quotation marks) that
specifies a GWBASIC program file. If the file is present,
GWBASIC proceeds as if a RUN 'filename' command were
given after
initi~ization
is complete.
A default extension of .BAS is used if none is supplied and
the filename is less than 9 characters long. The 'filename'
option allows GWBASIC programs to be run in batch by
putting this form of the command line in an AUTO-
EXEC.BAT file. GWBASIC programs which run this way
will need to exit via the SYSTEMcommaIid in order to allow
the next command from the AUTOEXEC.BAT file to be
executed.
is a literal string (not included in quotation marks) for the
standard input file specification. GWBASIC input is
redirected from the file specified by 'stdin'. When present,
this syntax must appear before any switches. (See "Re-direc-
tion of Standard Input and Output below.)
