GRAPH functions perform
library management tasks from within the DATA Step Graphics Interface.
These functions can be performed only on one catalog at a time. They
cannot be performed across catalogs. For example, you cannot copy
a graph from one catalog to another.
When using GRAPH functions,
remember the following:
-
All arguments are specified as
variables or constants. If you express an argument as a variable,
the variable must be initialized.
-
All character arguments expressed
as character strings must be enclosed in quotes.
-
All character variable names used
as arguments must be declared in a LENGTH statement.
-
All character constants must be
enclosed in single or double quotes.
