## What is a Macro ?

Macros are files, which contain a sequence of CAD-commands. The structure of CAD-commands is described under chapter 'Fundamentals of macro technique'.

Deviating from inputs via interface macros may contain some language constructions which cannot be put in interactively (e.g. loops, macro questions, temporary names).

Within each line describing comments may be placed behind '#'. If the interpreter finds this character, the rest of the line is ignored. This character is not interpreted in such a way if it is situated within constant texts.
