OV5.2 EDITING AN EXISTING PROGRAM
When editing an existing program in the CR510,
entering a new instruction inserts the
instruction; entering a new parameter replaces
the previous value.
To insert an instruction, enter the program table
and advance to the position where the
instruction is to be inserted (i.e., P in the data
portion of the display) key in the instruction
number, and then key A. The new instruction
will be inserted at that point in the table,
advance through and enter the parameters.
The instruction that was at that point and all
instructions following it will be pushed down to
follow the inserted instruction.
An instruction is deleted by advancing to the
instruction number (P in display) and keying #D
(Table 4.2-1).
To change the value entered for a parameter,
advance to the parameter and key in the correct
value then press A. Note that the new value is
not entered until A is keyed.
