LCWORD3: Converting a String to Mixed-Case

How to:

The LCWORD3 function converts the letters in a character string to mixed-case by converting the first letter of each word to uppercase and converting every other letter to lowercase. In addition, a single quotation mark indicates that the next letter should be converted to uppercase, as long as it is neither followed by a blank nor the last character in the input string.

For example, 'SMITH' would be changed to 'Smith' and JACK'S would be changed to Jack's.

Syntax: How to Convert a Character String to Mixed-Case Using LCWORD3 

LCWORD3(length, string, output)

where:

length

Integer

Is the length, in characters, of the character string or field to be converted, or a field that contains the length.

string

Alphanumeric

Is the character string to be converted, or a field that contains the string.

output

Alphanumeric

Is the name of the field that contains the result, or the format of the output value enclosed in single quotation marks. The length must be greater than or equal to length.

Example: Converting a Character String to Mixed-Case Using LCWORD3

LCWORD3 converts the strings O'CONNOR’s and o’connor’s to mixed-case: 

DEFINE FILE EMPLOYEE
MYVAL1/A10='O'CONNOR'S';
MYVAL2/A10='o'connor's';
LC1/A10 = LCWORD3(10, MYVAL1, 'A10');
LC2/A10 = LCWORD3(10, MYVAL2, 'A10');
END
TABLE FILE EMPLOYEE
SUM LAST_NAME NOPRINT MYVAL1 LC1 MYVAL2 LC2
END

On the output, the letter C after the first single quotation mark is in uppercase because it is not followed by a blank and is not the final letter in the input string. The letter s after the second single quotation mark (') is in lowercase because it is the last character in the input string: 

MYVAL1      LC1         MYVAL2      LC2       
------      ---         ------      ---       
O'CONNOR'S  O'Connor's  o'connor's  O'Connor's
