Math & Science ⇒ Why is this simple macro gives an halting problem?

[Cham]

I just defined this simple macro:

\newcommand*{\dp}{\hspace{0.5pt}}

Then, using \dp in mathmode gives an halting error:

Missing number, treated as zero.

and

Illegal unit of measure (pt inserted).

So what is wrong with calling my macro "dp" ? Three letters keyword works: "dpt", but why two letters gives a problem?

Hi Cham,

I guess that's because \dp is a TeX command for the depth of a box.

Hmm, I searched for \dp and found nothing on the net about this command.

I replaced it with \ssp and \tsp (for small space, and tiny space), so no harm!

Thanks Stefan.

No minimal working example?
