getHighKey

This function returns the character key with the highest sort rank for the given collation.

You can use this character to make a high key. For example, to search all customer names from “A” to “B,” inclusive, you can use the following:

ASSIGN low = "A"        high = "B" + getHighKey(session:cpcoll). FOR EACH customer WHERE custname >= low AND custname <= high.

If you are preparing to use the COMPARE statement or COLLATE phrase with a specified collation table name, then you can supply that table name to this function to get the high key for that collation.
