Can i have an optimized method for the task below. My copybook is very long..
File aid the input file using the copy book and see what comes as low values in the file - Do a hex on for low values/high values -Mention those fields in copybook that are normally blank or possibility of having high/low values
review Your understanding of the "null value" concept...
there is no such a a thing as a null value, every byte of eight bit is a value,
nullness is a convention to indicate that a value is not provided
to provide support for NULLNESS each data field must be composed of two parts...
NULL indicator ( tells if a value has been provided )
DATA value relevant only if NOT NULL
