Table parameters and array parameters allow a block (generic name of a table or array) and its associated dataset to be specified by a single parameter, using a colon-separated pair of the form set:table or set:array.
Block parameters are used where the value may be either a table or an array. This is appropriate for tasks which can perform generic operations, such as deleting a block.
Examples:
foo.FIT:R1SPE1 # Table R1SPE1 in set foo.FIT
/data/bar.FIT:FILTER_U # Array FILTER_U in array bar.FIT
The SAS GUI allows a block, table or array to be selected in a single operation, using a dataset browser. This is simpler than entering separate parameters for the dataset and block-name.
