Re: [NTG-context] Commands based on previously defined commands, with fixed values for arguments

Are there any rules where the space should be and where it should not?

The way you wrote the macro originally, the spaces were part of the macro. If you use your original definition of \HelloTwo, you can write \HelloOne as follows: ---- \def \HelloOne #1 {\HelloTwo {#1}{Vedran} } ---- and it works. \GoodByeOne{Arthur}
