Use the READDVAL statement to assign the current contents of the &SYSDVAL control variable to one or more specified symbolic variables.

The assignment is done sequentially to the variables in the order specified; variables not assigned values default to null values. If there are more values than variables, the excess values from &SYSDVAL are not assigned.
