JiffyDOS

Function Key Definitions

  • f1 Display the directory
  • f3 Load a BASIC program
  • f5 Load and run a BASIC program
  • f7 Load an ML program
  • f2 List a BASIC program from disk
  • f4 List an ASCII (text) file from disk
  • f6 Save a BASIC program
  • f8 Scratch a file

The JiffyDOS function key definitions have been designed to work along with the filenames in the directory listing. Once the directory has been listed, the cursor can be moved to the line of the desired filename, the appropriate function key can be pressed, and then RETURN can be pressed when it is OK to proceed with the command.

Using the JiffyDOS function keys with the directory listing eliminates the possibility of filename misspellings. And, there is no need to enter a colon (:) after the filename or erase the filetype characters manually in order to avoid a syntax error. After the function key has been pressed, the filename can be altered if desired.
