This command takes a screen file (which must have been created with COMPRESS), and re-expands it on the visible screen.
EXPAND needs a working space of 32K. A memory overflow error will be reported if there is not enough memory available.
EXPAND assumes that the screen starts at $20000 and will therefore not work on Minerva’s second screen or extended resolutions.
EXPAND will not work on QLs with resolutions above 512x256
If the file was not saved by COMPRESS, it is most likely that the system will crash. This is certain if the file is longer than 32K.
