Screen Editor This Chapter briefly describes the operation of the T-60’s built-in screen
editor. For a detailed description of the built-in screen editor, refer to the
EMERSON EMC BASIC PROGRAMMING GUIDE. This editor allows the
programmer to edit programs directly on the T-60’s screen without a PC
attached. This feature is most useful for program debug or for constructing
and modifying short programs. We recommend that you utilize the
ApplicationBuilder to generate more substantial programs. The
ApplicationBuilder will shorten your development time, give you much more
accurately generated BASIC code, and provide a means of storing,
documenting and cataloging your programs.
Editor Capabilities
The built-in screen editor has a complete set of features which allow the
programmer to develop programs directly on the T-60’s screen. Operation of
the editor requires the connection of an external PC-XT keyboard (see section
“Getting Started”). Once the keyboard is connected, you can access every
programmable function in the T-60. The editor capabilities center around the
T-60’s 8 line by 40 character display. It has a built-in 50 line scroll buffer
which can be used to view sections of programs (or entire programs if they
are short enough). The editor has the following feature set:
Line oriented editor - change a line by over-typing on it, press ENTER and
it is modified in the BASIC program.
78 character line capability. The editor can edit lines longer than the
screen width. If you keep typing after the first 40 characters, the editor will
insert a “¦” character at the end of the current line and the beginning of the
next line. You may continue typing on the next line. The “¦” characters do
not consume space in your program memory.
Full cursor control: Up, Down, Left, Right, Page-Up, Page-Down, Home,
End, Insert, Backspace, and Delete
Special functions: Control-Y stop program execution and return to the
editor; Control-T Delete to end of line.
Active function keys:
F1 RUN ←
F2 LIST
F3 REMOT ←(remote on/off *)
F4 CONT ←
F5 AUTO
F6 EDIT
* Useful for uploading and downloading programs with programs other than
the ApplicationBuilder. See the REMOTE Statement in the EMERSON
EMC BASIC PROGRAMMING GUIDE.
NEW command erases the contents of the editor memory.
