Comments

Most PAL printers with front panel displays have the ability to display a cursor on the display.

Presentation of a cursor can prove very useful when requesting input from the printer operator via

the front panel. The

_dspmovecursor

operator provides the PAL programmer with the ability to

locate this cursor where ever appropriate.

The PAL interpreter maintains separate locations for the visible cursor and the invisible next

character position. This allows the PAL programmer to write new characters onto the display

without affecting the position of the visible cursor.

Under normal printer operation, the PAL interpreter leaves the displayable cursor disabled. This

has the affect of removing the cursor from the display. The PAL programmer can freely move the

display cursor around the display. However, the operator will not see the cursor until the

programmer enables the cursor via the

_dspsetcursor

operator. Once the programmer enables the

cursor, it will appear at the last cursor position established via the _dspmovecursor operator.
