Function or Procedure

[krishnaroopa]

What are the factors to be considered to write a method as Procedure or function?

Yes, of course, Function has return value. but i can return this value as out parameter through a procedure also.

[dineshasanka]

if UR using procedure


call ProcedureName(parameters)
if returnvalue = true then

endif




if UR using Function


if FunctionName(parameters) = true then

endif
