Editing a Program
You can modify a program in program memory by inserting, deleting, and editing
program lines. If a program line contains an equation, you can edit the equation.
To delete a program line:
1. Select the relevant program or routine and press
Ø or × to locate the
program line that must be changed. Hold the cursor key down to continue
scrolling.
2. Delete the line you want to change —press
directly (Undo function is
active). The pointer then moves to the preceding line. (If you are deleting more
than one consecutive program line, start with the last line in the group.)
3. Key in the new instruction, if any. This replaces the one you deleted.
4. Exit program entry (
or ).
To insert a program line:
1. Locate and display the program line that is before the spot where you would
like to insert a line.
2. Key in the new instruction; it is inserted after the currently displayed line.
For example, if you wanted to insert a new line between lines A004 and A005 of a
program, you would first display line A004, then key in the instruction or
instructions. Subsequent program lines, starting with the original line A005, are
moved down and renumbered accordingly.
To edit operand, expression or equation in a program line:
1. Locate or display the program line that you want to edit.
2. Press Õ or Ö to start editing the program line. These turn on the “_”
editing cursor, but do not delete anything in the program line
Õ key actives the cursor to the left of the program line
Ö key actives the cursor to the end of the program line
