Record evaluator

 

evalrecs	Evaluate data records using a macro
-d <datain>	input data
-dout <dataout>	temporary output data
-mac <macro>	name of the macro file

This operation evaluates data records of the source data with a given macro. The procedure is as follows:

 
For each record    in <datain>

		 Copy    to a data frame <dataout>

		 Execute: runcmd <macro> <dataout>

		 Delete <dataout>

End

One parameter, the name of the temporary output data, is passed to the <macro>. Another important point to note is that the output data is deleted after the macro has been executed for a data record. More information about running command files can be found in section 8.4.
