Hello,
is there a way of getting the horizontal and vertical cursor position in MMBasic for DOS, like HPOS and VPOS for the CMM?
Thanks.

Hi hkoetz

Welcome to the Forum.

Have you checked out the MMDOS manual downloadable from here (Bottom of the page)

This will give the list of commands & functions which MMDOS does & does not support & other valuable information.

I think you will find that MMDOS does NOT support graphics. (but I could be wrong)

Thanks Brian,

MMDOS indeed does not support graphics. It has a command Cursor which positions the cursor on the console screen (column, row) in characters. I guess I should have asked if the reverse of this command is available in some way: getting the position of the cursor on the console screen. There is not a direct basic command for this. Is it possible to use some lower level command for this?

Best

Henk,

The function POS will return the current cursor position (in characters) in a line, eg.

PRINT "abc";:PRINT POS

will return

abc 4 ( that is, the cursor position is the 4th character position immediately after the c in the string abc.

As far as the actual line number, MMBasic for DOS appears not to track this in normal program execution other than to just feed carriage return or new line through to Windows which scrolls the display window.

The EDITOR command is a special case where MMB tracks the cursor position but this does not appear to be accessible outside this command ( and would not be relevent anyway).

Hope this helps,
Doug.
