NAME

xbasic,x11basic,X11-Basic - The BASIC language interpreter and shell  

SYNOPSIS

xbasic [--eval <expression>] [-e <command>] [-l] [<filename>]

 

DESCRIPTION

X11-Basic is a dialect of the BASIC programming language with graphics capability that integrates features like shell scripting, cgi-Programming and full graphical visualisation into the easy to learn basic language on modern computers.

The syntax is most similar to the old GFA-Basic ATARI ST implementation. Old GFA-programs should run with only few changes. Also DOS/QBASIC programmers will feel comfortable.

Ancient ANSI-Basic programs (with line numbers) can be converted to X11-Basic with the bas2x11basic program (see the man page bas2x11basic(1) ).

xbasic is the interpreter. It interpretes basic command-files (programs), which usually have the extension .bas or .xbas. It can also run in interactive mode in which case it interpretes single lines of code, which are entered.

 

COMMANDLINE OPTIONS

 

 <file>

load and run script <file>
 

-l <file>

only load script, do not execute
 

--eval <expression>

evaluate expression
 

-e <command>

execute command
 

-version

shows version, program and other information and exits  

-h --help

print a short help  

--help <topic>

print help on topic  

--daemon

daemon mode

For detailed help and description of the implemented basic commands take a look at the README file which comes with the X11-Basic package. There is also a full users manual available as *.pdf file on the homepage.

 

INTERACTIVE USE

If no options are given on the command line, xbasic will run interactivly.

A prompt will be displayed and any command can be typed in. It will be excecuted immediately after pressing return or enter. The input is buffered and can be edited using the up and down arrows on the keyboard.

To quit the program simply enter quit or press CTRL-C.

 

EXAMPLES

xbasic testme.bas
xbasic -e 'alert 1,"Hello world !",1," OK ",b'
xbasic --eval 1+3-4*3
xbasic --help "*nl*"

You can find many sample programs in /usr/share/doc/packages/X11Basic/examples.

 

X11-Basic as daemon:

The commandline option --daemon forces the interpreter to run in daemon-mode (with no terminal connected). No prompt is given and the input is not echoed back.

 

X11-Basic as shell:

X11-Basic programs can be excecuted like shell scripts. If the xbasic interpreter was installed in /bin/ any X11-Basic program with
 #!/bin/xbasic
in the first command line can be excecuted directly.
