One of the essential points with a procedure like CAP is, as was stated,
speed.
But then, if this really was the main point when implementing CAP, I can't
understand the output of the following module

MODULE PrivCapTest;

        IMPORT
                Strings, In, Out;

        PROCEDURE Do*;
                VAR
                        ch, CH: CHAR;
                        i: INTEGER;
        BEGIN
                FOR i := ORD(MIN(CHAR)) TO ORD(MAX(SHORTCHAR)) DO
                        ch := CHR(i);
                        Out.Ln;
                        Out.String("CAP(CHR(");
                        Out.Int(i,0);
                        Out.String(")) = ");
                        Out.String("CAP(");
                        Out.Char(ch);
                        Out.String(") = ");
                        Out.Char(CAP(ch));
                        IF ch = CAP(ch) THEN
                                Out.String(") = ");
                                Out.Char(ch);
                        END;
                END;
        END Do;

END PrivCapTest.

When you look at the output you will remark quite a lot of characters (of
different gender, i. e. 'letter' and non 'letter') being mapped onto
themselves whereas others of similar gender are not. So, if despite of
speed it is possible to do this mapping why isn't it possible in the rest
of the non sense cases resulting an intuitively understandable and at the
same time foolproof function?
