VLISP has a powerful feature for checking your code for syntactical errors. Use this tool before trying to run the program. You can catch common typing errors, such as missing parentheses or missing quotation marks, and other syntactical problems.
The Build Output window is displayed with the results of the syntax check. If VLISP did not detect any errors, the window contains text similar to the following:
[CHECKING TEXT GPMAIN.LSP loading...]
; Check done.
If you have problems and need help, refer to the ÔÇťDeveloping Programs with Visual LISPÔÇŁ section of the AutoLISP Developer's Guide. See if you can determine where the problem is located. If you are spending too much time locating the problem, use the sample gpmain.lsp file provided in the lesson1 directory to continue with the tutorial.
