The statements in a macro usually have parameters that need to be
assigned values. Parameter tables provide a very efficient way to run
a macro repeatedly with different sets of parameter values. Parameter
tables are scrollsheets in which macro parameters are represented by
columns whose cells contain the actual values for the parameter. The
macro is executed once for every row of parameter values in the table.
This feature is similar to mail merging in a word processing program.
