MACRO Power (review)
|
|
Without loops and sub-programs there would be no computer software.
A new program would have to be written for every task.
Yes, it is possible to implement sub-programs with branches,
but like any living tree with many branches it is almost
impossible to rid them of bugs.
The power of sub-programs that can be executed with varying parameters cannot be overemphasized. It seems magical when you see how much can be done with so little code. The GHS command language provides a construct called a MACRO with which you can make your own sub-programs and enjoy the power of creation. (Additionally there is the ROUTINE.) The geometry model shown rendered in the image below, which was created with Part Maker, demonstrates the power of the MACRO. It consists of 1,692 shapes using a series of commands that is far fewer than that! |
