What does the error message "COMP96 ERROR COMP96_0018: 'Identifier expected.' 'design.vhd' 18 24" mean?

edit

This error message indicates that there is an identifier missing at line 18, column 24 in the file "design.vhd". An identifier is a name given to a variable or object in the code, and it is expected to be present at that location. It might indicate a syntax error or a missing declaration that needs to be added to the code at that point.
