Subject:      A Macro Problem (ref.: SUGI Paper 100-27)

Hi out there!

I found this little Macro in SUGI Paper 100-27 (Carpenter).

%macro exists(dsn);
        %sysfunc(exist(&dsn));
%mend exists;

As one can see it is very simple and it's task is easy to understand.

I'm quite new to SAS and now I'm getting following log messages which
I don't know to interpret:

5285   %exists(temp1e);
MLOGIC(EXISTS):  Beginning execution.
MLOGIC(EXISTS):  Parameter DSN has value temp1e
SYMBOLGEN:  Macro variable DSN resolves to temp1e
NOTE: Line generated by the macro function "SYSFUNC".
1       1
        -
        180
MPRINT(EXISTS):   1;

ERROR 180-322: Statement is not valid or it is used out of proper
order.

MLOGIC(EXISTS):  Ending execution.

The Dataset exists, the macro resolves to the right value and give the
right output but there is some error which I don't know to eliminate.
Any hints what I'm doing wrong?

Thank You in advance.
