Execution of CLC-INTERCAL program can produce many errors, one of the most common is attempting to
execute a comment. Errors are reported using a splat, consisting of an error code and an error message.
The splat code is also available in the special expression * after the error occurred: this is only
useful when the program is multithreaded (another thread produced the splat) or within events, as
producing a splat is always fatal and causes the program to terminate.
When printing a splat, the format will always be:
*nnn message
where nnn is the splat code. See file blib/htmldoc/errors.html in the distribution build directory (or
the corresponding page in the online reference manual) for a list of splat codes.
