# System Parameters

'DC' | Destructive Cursor

## Description

Sets destructive cursor. (Moving from left to right, replaces intervening characters with spaces up to the new cursor position.)

## Default

Off - The cursor jumps over the intervening characters.

## Example

> set_param 'DC'=0
> print @(15),"B",@(10),"A",@(20),"C"

With 'DC' Off, the screen output is "A B C". The cursor jumps first to column 15 and prints the B, jumps to column 10 and prints the A, then finally jumps to column 20 and prints the C.

> set_param 'DC'
> print @(15),"B",@(10),"A",@(20),"C"

With 'DC' On, PxPlus uses a destructive cursor (line print mode, as in BBx® and some MAI systems). The preceding example would result in " A C" because the output driver simply issues spaces when advancing on the same line. With 'DC' On, after printing the B and A, the driver uses 9 spaces to position itself at column 20 to print the C. The destructive cursor overwrites the B with the space.
