GImmy ,

Ill skip the Macro design issues and the resulting data step code issues
since we need for the time being to focus on a more basic issue.

In teh macro facility there are 2 types of comments the /* <some text */
and %* <some Text> ; I would say the easiest and safest to use in a %Macro
is the %* <text> ; form I say this because you can have some issues with
commenting when you use /* <text here> */.


The *<Text> ; is only valid in open code.  This explains why you see some of
your macro variables getting resolved.  YOu havent commented them out from
the macro facility.

Just because you comment every thing between the %Macro and %Mend doesnt
mean nothing will be put to the log, in fact when SAS compiles the macro
definition it will echo the definition to the log.

Hi all,
I wrote a macro that can do somthing. The funny thing is that if I put
all the codes in this macro as comments, it runs as if these codes
were actually executed.  The macro is put below. As you can see, all
the lines except the header and end are commented and there should be
NO output in the log window. However each time I submit
this script the lines of ''%put &numfiles'' and ''%put &filename1''
are read and the results will be written in the log window.
Can anyone kindly bring some idea of this happening?
Thanks!
gim
