Displaying Current Values Using the Refer Operation

If the cursor is on the SEE instruction or a user function symbol, the SEE instruction or user
function symbol will be expanded into the drawing program or user function program using
the refer command. Accordingly, the current values when the SEE instruction or the FUNC-
TION CALL instruction (FSTART) is executed can be displayed.

Move the cursor to position (A) in DWG.L in the following diagram, and execute the refer
operation to open the DWG.L01 Program Window. The current value displayed for
DWG.L01 will be the value displayed when the SEE instruction is executed at position (A)
in DWG.L. The value when the SEE instruction is executed at position (B) will not be dis-
played.

The procedure to display current values using the REFER instruction is outlined below.

1. Move the cursor to the drawing number or function symbol position for the SEE or

FSTART instruction.

2. Select Debug (G) and then REFER (R) from the programming menus.

The program window being called will be displayed.
