Examples

Example 8-158 Converting Part of a Text Expression to Uppercase

Suppose you get some new data to add to a mailing list. In the existing mailing list, people's names have the first letter capitalized. In the new data, however, the whole name is in lowercase. You can use UPCASE to make the new data correspond to the current data with a statement similar to the following.

lastname = JOINCHARS(UPCASE(EXTCHARS(lastname, 1, 1)), -
           EXTCHARS(lastname, 2, NUMCHARS(lastname)))
