My program London for the Epson HX-20 (issue 74) will stop with:
Out of string space
if you enter lengthy from and to addresses.
This can easily be prevented by inserting in line 140, after WIDTH24,20:, the command CLEAR 400:.
The TAB key should not be used when entering multi-line addresses, or the computer will ignore whatever precedes the tabulation. Use the space bar instead if you want to get to the next line when writing an address.
