Debugging is the process of testing the logic of the program.
To debug the sas Datastep: use the Debug clause after '/' in
the data statement and execute. If needed set watch points,
and keep on pressing enter key while Observing the values
in the debugger log window.Finally exit from it.
To debug the Macro programs, use the system options like
Symbolgen,Mlogic, Mprint.
Debugging is also supported by the log window by
notes,warnings, errors and messeges of and Error macro
variables.
