$ZU Functions

$ZU Functions

In existing code, you might see items like $ZU(n), $ZUTIL(n), $ZU(n,n), and so on, where n is an integer. These are the $ZU functions, which are now deprecated and are no longer documented. They are still available, but users are encouraged to replace them with methods and properties in the Caché class library that perform the equivalent actions. There is a table of replacements in “Replacements for ObjectScript $ZUTIL Functions” in the Caché ObjectScript Reference.
