## Syntax Rules

When SISCAD-P commands are entered, certain rules must be followed, so that the system understands the contents of the commands, interprets them in the right way, and executes them correctly.

1. The order action-object-characterization-parameter must always be followed.

2. In front of the first parameter, at least one ' ' (blank character) must be entered.

3. Parameters are separated by a '; ' (semicolon).

4. To terminate a command, a '! ' (bang) is necessary.

5. The commands are always written in capital letters.

When entering commands by mouse (within the CAD-command window) these rules, explained above, are automatically observed.
Above all the syntax rules has to be in consideration by the macro programming and when entering commands by keyboard.
