Filename is limited up to 16-characters' long and must be enclosed in double quotes ( " ) as in "BASIC".
Record the filename lest you forget it. The LOAD command will not be able to find the program you want unless you supply the correct filename to it.
Also it is a good idea to check and record the start and the end values of the tape recorder counter when you execute this command.
Do not forget to check whether the program has been correctly saved with the VERIFY command.
