* FT_PROPER()
|
|
* $CATEGORY$
|
|
* String
|
|
* $ONELINER$
|
|
* Convert a string to proper-name case
|
|
* $SYNTAX$
|
|
* FT_PROPER( <cString> ) -> cProperName
|
|
* $ARGUMENTS$
|
|
* <cString> is the string to be converted.
|
|
* $RETURNS$
|
|
* A string of the same length as <cString>, only converted to
|
|
* proper name case (upper/lower case).
|
|
* $DESCRIPTION$
|
|
* FT_PROPER() uses a brute-force algorithm to convert a string
|
|
* to propername case. First, it capitalizes the first letter of
|
|
* all words starting after a blank, dash, or apostrophe. This
|
|
* catches most names, including special cases such as names
|
|
* beginning with O' (O'Malley, O'Reilly) and hyphenated names
|
|
* (such as Susan Chia-Mei Lo).
|
|
*
|
|
* Next, it does a specific adjustment for words beginning in "Mc"
|
|
* It finds the first 'Mc' and capitalizes the next character after
|
|
* it. It does this for all occurrences of Mc.
|
|
*
|
|
* The original FT_PROPER() was written in Clipper by Glenn Scott
|
|
* and Mark Zechiel; it was re-written in C (and thus, optimized
|
|
* and enhanced) by Robert DiFalco.
|
|
* $EXAMPLES$
|
|
* FUNCTION main( cStr )
|
|
* OutStd( FT_PROPER( cStr ) + chr(13) + chr(10) )
|
|
* RETURN ( nil )
|
|
* $END$
