2.3.14 CURPOS variable
Description
Using the CURPOS variable, it is possible to display or manipulate the position of the cursor
in the active input field of the current dialog. The variable indicates how many characters are
located in front of the cursor. If the cursor is located at the start of the input field, then
CURPOS assumes the value of 0. If the value of CURPOS is changed, then the cursor is
positioned at the appropriate location in the input field.
In order to be able to respond to changes in the variable value, it is possible to monitor for
changes using a CHANGE block. If the value of CURPOS changes, then a jump is made to
the CHANGE block and the instructions contained there are executed.
