Record locking is supported (this depends on the OS). It comes with include files for each environment that needs to do weird things for record locking, so *you* don't have to figure it out. > 4.

You just tell it how long the fixed length portion is (must come first), how long is the maximum for the variable length portion, and it handles the rest automagically. > 5.

This means that you can open dozens of files in MSDOS, and it automatically closes the least-recently-used as you open each new file. When you need one that has been automatically closed, it automatically re-opens and repositions it. Works great! -- Mark D.
