## Macro Questions

It is possible, to leave some sequences within a command (i.e. parameter settings) open and to replace them by a question string.

The sytax of such a makro question is any text, which is enclosed with the special character '$'.

e.g.:

           CREATE LINE PP $  first point :  $;200,100!

In this example the interpretation is interrupted at parameter P1 and then a question window is opened, which contains the question 'first point'.

In this dialogue the user may carry out any inputs as far as they are syntactically correct and suitable for the part of the command that is to replace.

Backspaces are possible only up to the beginning of the question position. The answering of the question is terminated either with a return or a '!' in the command line or by pressing the right mouse key in the graphics window.

Theoretically any text sequence within a command may be replaced by a question string. (Exception: the execution of the command itself '!' cannot be replaced).
