BLOAD
by Mike Williams

This program will load and display any 25 x 80 text screen saved in
GWBASIC's BSAVE format.

Command syntax for BLOAD is:

BLOAD <filename>

The current screen is 'dissolved' to show the new screen. The program checks
to see if the named file exists, but does not validate it, beyond checking
that it's no bigger than 4k.
