The error you are seeing is from SKILL itself and on well written programs, end users should *NEVER* see such an error.Originally posted in cdnusers.org by J.C. Roberts
The (getc...) function takes a "port" which is also known as a "file
handle" (a pointer to an open file). The fact that it is being given
"nil" means opening a file failed and the program did not have
sufficient error checking to deal with this problem condition.
In other words, the program you are trying to run is failing to find a
file that doesn't exist or it is failing to open some file because of
access permissions (no read permission, a full hard drive, etc.). Your
guess which file this might be is probably better than mine.
hope this helps,
