Got some information ,,,,,,finally

Phew , finally my Team leadet taught me the basic concepts of COPYBOOK that we were using on out Development project. I (as usual )neglected that piece of code during testing and development phase but during my support phase i happen to see that 1 line of code…..huh…..took almost 1 day that day to understand and then  left that “1 piece of line”. Then realised that i should not neglect that code….i went to my Team Leader.She taught me how to use and showed me the variables defined in Copy Book statement…..

That line of code actually worked like an “inline function” . Only required when the same piece of code is required by number of API’s.
