What do you understand by passing by reference and passing by content?

Question Posted / babalu gautam


What do you understand by passing by reference and passing by content?..

Answer / robertd903

Passing by reference, is passing the ADDRESS of a variable--to a subprogram. The subprogram is able to change the value contained in the variable.

Passing by content is passing the DATA contained within a variable--to a subprogram. The subprogram can NOT change the value of the data in the (calling program's) variable.

In COBOL CALL-CALLING,if a program A is calling 3 sub- programs, dynamically, then it is said sub-programs will always will always in Initial Mode. My question is : Do we need to code CANCEL or (IS INITIAL) for dynamically called sub-programs or it is the property of Dynamically called pgms so every time sub-pgms are called they will be in initial mode. ***This question is only Dynamic call****, Please reply. Thank you in advance.
