New and Improved Features in PETRAPro
IMPROVED
File Handling
PETRAPro uses the latest in software programming techniques to provide you
the optimum user experience. One area where this is evident is the file
handling of the program. PETRA for Windows used temporary work files, so
that any time you opened a data file, six other temporary files were opened
and remained open until you closed the file. PETRAPro eliminates this
additional overhead by doing all work within one file.

Development on PETRA for Windows began in the mid-1990s and the
program was officially released in 1998. Since that time, many changes have
been made in software programming that allows today's programs to be more
efficient and faster than their predecessors. In addition to the file handling
improvements, the overall speed and stability of PETRAPro has been
improved from PETRA.
