I am running some VHDL through ModelSim. Each error and warning has its own error code (like this: (vcom-1292) Slice range direction "downto" specified in slice with prefix of unknown direction. This is just an example message; I understand what it means.
I assume that Mentor has a list of all possible error codes and a more elaborate description of what they mean, and how to avoid them. I did not find this error code in the PDFs that come with ModelSim, nor did I find it through Google. Any pointers anybody?

I resolved it by right clicking on the specific library and clicking "refresh". Then, I recompiled and restarted simulation, and it worked.
vmap. defines a mapping between a logical library name and a directory. vopt. produces an optimized version of your design.
You have the option of clearing the transcript (File > Clear Transcript) if you don't want to save the entire command history. To save the contents of the transcript select File > Save Transcript As from the Main menu.
There is a modelsim command called verror with an -all option to list them all, and other options to inspect the messages further.
