EXISTS
The EXISTS function determines whether an object is defined in any attached workspace. The EXISTS function is useful in a program to test whether a definition exists before you try to use it.
Syntax
EXISTS(name-expression)
Parameters
- name-expression
-
A text expression that specifies the name you want to test.
Usage Notes
Specifying More Than One Name
When name-expression contains multiple object names, EXISTS returns NO even when all the objects specified by name-expression exist in attached workspaces.
