The other indicator is the two line, 40 character LCD display. This display can be controlled
with specific Extended X Language commands. The Position Cursor (DPC) command allows
the user to program the location of the cursor on the LCD display. The 'Display Text Data on
RP240 Display' (DTXT) command allows the user to place text, beginning at the current
cursor location, on the LCD display. For example: A user wishes their operator to see the
message ENTER THE CYCLE COUNT. The user wants this message placed on line two,
starting after two spaces in from the left. Following the message by three spaces the cycle
count is to be entered, and stored in variable 1. Below are the steps required to accomplish
this.
The cursor does not appear on the display. The cursor is displayed when the VARn=NUM or
DPC commands are used.
Step 1
Issue the DPC202 command (line 2, position 02)

Step 2
