New version of Bas7 - Interpreter for old BASIC programs from the line number era
tm
I just released a new version of the Bas7 BASIC interpreter.
Bas7 can execute old BASIC programs from the line number era
(If you know GW-Basic: That was the era). Stuctured 'IF', 'DO'
and 'SELECT' statements and programs without line numbers are
also supported. The interpreter is released under the GPL and
it works under Unix, Linux, BSD, Microsoft Windows and
Mac OS X. A description of Bas7 can be found here:
http://seed7.sourceforge.net/scrshots/bas7.htm
The new version of Bas7 is contained in new the release of
Seed7 seed7_05_20091004.tgz, which can be downloaded at:
http://sourceforge.net/project/showfiles.php?group_id=151126
Changelog of the 2009-10-04 version of bas7:
- The handling of 'NEXT' statements with several variables
(e.g.: 'NEXT I,J,K') was improved.
- Statements starting with the letters of a keyword which cannot
be recognized as 'LET' statements are handled as if a space is
inserted after the keyword. E.g.: 'GOTO250' is equivalent to
'GOTO 250'.
- When a certain keyword is expected and the current symbol
starts with this keyword a space is silently inserted after
the keyword. E.g.: 'IF I=5 THENI=2' is interpreted as
'IF I=5 THEN I=2'.
- When a 'LET' statement starts with the letters 'IF' and the
statement is followed by the letters 'THEN' it is interpreted
as 'IF' statement instead. E.g.: 'IFI3=5*J THEN 100' is
interpreted as 'IF I3=5*J THEN 100'.
- When a 'LET' statement starts with the letters 'FOR' and the
statement is followed by the letters 'TO' it is interpreted
as 'FOR' statement instead. E.g.: 'FORJ1=3*I TO 7*I' is
interpreted as 'FOR J1=3*I TO 7*I'.
- The handling of 'BLOAD' was improved to support loading even
when the file contains data for several arrays.
- The reinterpretation of array contents as pixel images was
improved.
- The function 'VARPTR' was added.
It would be nice to get some feedback about it.
