Specifying the Source File

Go Up to Preprocessing

Because both the language switch and the filename extension are optional, gpre can encounter three different situations:

• A language switch and input file with no extension
• No language switch, but an input file with extension
• Neither a language switch, nor a file extension

This section describes gpre’s behavior in each of these cases.
