- Howdy netters,
-
- I am trying to develop a routine to edit text in graphics mode.
-
- Background:
-
- MSC 7.0
- Miscrosoft supplied graphics library
- The mode under consideration is 640*480*16 VGA mode.
-
- As part of the routine, I need to display a cursor on the text so that
- the user knows which position of the text is being edited and
- accordingly can use keys like INSERT, DELETE, LEFT, RIGHT etc. A
- flashing vertical line between the characters would suffice for this
- purpose.
-
- The problem is, there doesn't seem to be any cursor routine defined
- in the microsoft graphics library. I tried using int10h services
- for change cursor size and shape (01h) and set cursor position (02h).
- But nothing appears on screen and the return values for these services
- are not defined either.
-
- Can someone suggest me where I am going wrong, or if there is an
- alternate solution to this problem.
-
- Thank you for your help.

- PS: Microsoft Windows uses a flashing vertical line for editing purposes.
