I seem to recall a discussion on this list recently about printing
terms in text in bold the first time they are used in a document, then
in normal font after that. I think the solution involved ifthen

I have a similar situation. I use macros to insert boilerplate
responses to submitted questionaires. The macros can include graphics,
and can be used more than once. I would like the graphics to be
used only once (to save space and avoid multiple labels).

Is there a way to check if a macro has already been used, and
treat it differently on subsequent uses?

In other words, the macro  \AnswerOne may be defined as:

so that \FigureOne is expanded the first time but empty on subsequent

I'm familiar with basic LaTeX, but I'm not a programmer, so the
ifthen documentation is a little daunting. Sorry if it seems obvious.

Many thanks
