Finding the version number

by Richard Russell, January 2010

You can discover the version number of BBC BASIC for Windows using the following procedure:

      DEF FNversion
      LOCAL F%, V$
      F% = OPENOUT(@tmp$+"version.txt")
      OSCLI "OUTPUT "+STR$F%
      *HELP
      *OUTPUT 0
      PTR #F% = 0
      INPUT #F%,V$
      CLOSE #F%
      = RIGHT$(V$,5)

You can call the procedure in a context such as this:

      version$ = FNversion
      PRINT version$
