The Image Database information is returned in both the ALPHA register and the display,
in the format shown below. Since a module image may be up to 32K in length (8 pages),
more than one physical address can return with a match, but only the information in the
actual database entry is returned. If no address match is found the function will result in a
NO MATCH
error message. Only the first match (the search proceeds from lowest
database address upwards) will ever be returned.

This function automatically executes the search in the 50X Turbo mode, but even so the
search may take several seconds when searching for an address match. A

message is written to the display while a search is in progress.
