hi to all,
can any body clearly explain wat is copy book? where it resides and used? how it is related to main programs?. i already see this forums so plz don't mention any old topic by specifying links. i can't get a clear idea.
and also say about what is UNIT TESTING? how it is performed ? plz don't mention old links reply as soon as possible plz
Copybook is our private lib.which is created by self.u can create it like a member.suppose u want to use same record structure in diffrent programmes,then u can declare those structure in ur copy book and in ur programme used that copy book using copy command in working-storage section.those structure will be part of ur programme.
UNIT testing is the primary phase of testing .when we perform the testing operation at unit level.every programme will be check individualy(i.e syntax checking,flow checking).it is primirialy done by developer.
Anybody can correct it.Please.
