Re: Drop Case API

[Jeff Young <cooljeff913@xxxxxxxxx>]

Rory,
That is what I am looking for.
A method to convert a text string from all upper case to a string where the first letter of each word is upper case and all others are lower case.
The words are separated by a blank.

It looks like your example will do what I want.

Thanks,

I assumed Jeff meant "1st-letter-upper-otherwise-lower". Hence the casing of
his question:

CASE to Drop Case?

Any, the quick answer is that there isn't a single API. However, you could
do something like this (untested):

string = %xlate( UpperChars : LowerChars : string );
ConvertToUpper = *off;
for x = 1 to %len( string );
  char = %subst( string : x : 1 );
  if ConvertToUpper = *on and char <> ' ';
    string = %xlate( LowerChars : UpperChars : char );
    %subst( string : x : 1 ) = char;
    ConvertToUpper = *off;
  else;
    if char = ' ';                    <=======
      ConvertToUpper = *on;
    endif;
  endif;
endfor;

Although maybe you only want to capitalize the first letter in a sentence,
so you'd use this at <=======:

    if char = '.' and %subst( string : x + 1 : 1 ) = ' ';

although that would throw an error if the last character in the string is a
period. Plus you'd be better off basing char on a pointer, to avoid all
those silly substrings back and forth.

And maybe I was wrong about what Jeff wanted anyway.
