Text Formatting ⇒ Test for Space as next Character

[Laurentius]

I tried \@ifnextchar\space and \@ifnextchar\@sptoken to check if the next character was a space, but it didn't work.

Can you show us for what purpose or in what cases you want to test for a space? It might be easier to look for everything than a space...

\@ifnextchar deliberately skips spaces, so this will not work! As suggested, the use case might be handy here so we can suggest a good solution.

amsgen (amsmath) provides \new@ifnextchar that can be used instead of \@ifnextchar if following spaces shouldn't be ignored, so maybe that might work.
