CCUR-After SPLOT, uses graphics cursor to indicate data values

Description:

If a spectrum has been displayed on the current soft plotting device, CCUR allows the user to move the cursor around the display, indicating the current cursor position and data value each time a terminal key is pressed.

Parameters:

SCREEN

The screen management routines used by CCUR do not know how to handle all the various types of VDU. If you find that you are having problems getting output from CCUR, try setting SCREEN=NO - this bypasses the fancy screen formatting and puts out the data crudely but directly to the terminal as though it were not a VDU.
