A CIF may contain data names in upper, lower or a mixture of cases. Internally, CIFtbx does all its name comparisons in lower case, using the function locase (see above) to convert. Good style, however, dictates the use of certain case combinations in certain names. Therefore CIFtbx does this lower-case conversion as needed, preserving the original case for whatever use may be desired. An application needing maximum speed and which does not need to preserve the cases in the original CIF might consider doing the case conversion once and removing the use of locase.
