Comments in AutoLISP Program Files
 
 
 

It is good practice to include comments in AutoLISP program files. Comments are useful to both the programmer and future users who may need to revise a program to suit their needs. Use comments to do the following:

Comments begin with one or more semicolons (;) and continue through the end of the line.

; This entire line is a comment

(setq area (* pi r r))  ; Compute area of circle

Any text within ;| ... |; is ignored. Therefore, comments can be included within a line of code or extend for multiple lines. This type of comment is known as an in-line comment.

(setq tmode ;|some note here|; (getvar "tilemode"))

The following example shows a comment that continues for multiple lines:

(setvar "orthomode" 1) ;|comment starts here

and continues to this line,

but ends way down here|; (princ "\nORTHOMODE set On.")

It is recommended that you use comments liberally when writing AutoLISP programs. The tutorial files provided with VLISP contain good examples of commenting style. If you've installed the AutoLISP Tutorial files, you'll find the AutoLISP tutorial code in the Tutorial\VisualLISP directory.
