FILENAMES UPPER_CASE LOWER_CASE MIXED_CASE [SEARCH]
Mixed case uses the NAME= string unmodified, and permits searching only on Unix when no case sensitive match is found. Other platforms ignore the SEARCH keyword.
Long Filename Support
Version 3.9 supports long filenames with a variety of alternatives with respect to case sensitivity. Unix defaults to case sensitive, and Windows defaults to case insensitive. Business Rules! defaults to lower case on all platforms, unless overridden by a FILENAMES configuration statement.
Specify FILENAMES LOWER_CASE when running both Windows standard model and Linux/Unix client server at the same time. This will align file naming between the two platforms with maximum processing speed.
