Now I have implemented the -p option for Bas7.
Bas7 can now be called with:
  ./hi bas7 -p foo.bas

With the -p option bas7 asks for a prompt at the end of the
program. The new version of Seed7 and Bas7 is contained in
the seed7_05_20080319.tgz package which can be downloaded at:

http://sourceforge.net/project/showfiles.php?group_id=151126&package_id=167035&release_id=585431

Features of the improved Bas7 interpreter:
- DEFINT and DEFSTR with overlapping ranges were improved.
  New DEFINT or DEFSTR statements which have overlapping
  ranges compared to previous DEFINT or DEFSTR statements
  just shrink the range of the prefious statement.
- Bas7 now supports FIELDS which can be used for file
  input and output.
- Support for the statements GET and PUT which read and
  write file records (described with FIELD statements) was
  added.
- Support for the statements LSET and RSET, which left- or
  right-justify the value of a string in a string variable,
  was added.
- The support for the functions MKI$ and CVI is also new.
- The OPEN statement was improved.
