Re: Ada facility for determining dimensions (height/width) for display/print character string?

["Russell L Johnson" <russjohnson@frontiernet.net>]

The text will be in Windows and it looks what I need is either
Graph.TextHeight (and Graph.TextWidth) or the Windows GetTextExtent function
[unless I decide to use TeX or PostScript :^) ].

Thanks to all for your helpful information. Sorry I accidentally posted my
original post twice.
