Question: What are the Cursor Positioning techniques in CICS?

Answer: Static Cursor Positioning : When defining the map field DFHMDF macro in the attribute parameter IC is coded, the cursor will be positioned in that field. This method of cursor positioning is called static cursor positioning Relative Positioning : Code the CURSOR option with a value relative to zero Symbolic Positioning : Move high values or –1 to the field length in the symbolic map and code CURSOR on the SEND command.

There are three types of cursor positioning techniques.

1.Static cursor POsitioning:

This is normally we code at the time of creating a map.
eg: name DFHMDF POS=(2,6),LENGTH=15,ATTRIB=(IC,UNPROT,FSET),PICIN='X(15)',INITIAL='_______'

here IC stands for Initial Cursor Position(place the cursor initially on this field).

2.Dynamic Cursor Positioning:
By moving the -1 to the Field name+L field in the application program.and send the map to the terminal with CURSOR option .

3.Relative positioning:

Byplacing the CURSOR(pos) while sending the map in the SEND MAP command.
