When the macro processor begins compiling a macro definition, it reads and

compiles tokens until it finds a matching %MEND statement. If you omit a %MEND

statement or cause it to be unrecognized by omitting a semicolon in the preceding

statement, the macro processor does not stop compiling tokens. Every line of code you

submit becomes part of the macro.

This kind of error is known as "BLACK HOLE ERROR" in SAS.

To recover from this error, submit the followin:

');

%mend;

If the above method dont work, submit the following:

*’; *"; *); */; %mend; run;

Continue submitting this string until the following message apperas in SAS Logs:

ERROR: No Matching %MACRO Statement for this %MEND statement.

If still problem not resolved after applying above methods, YOU HAVE TO CLSE THE SAS SESSION...MAKE SURE YOU SAVE ALL YOUR RELATED WORKS...

Hi,

Further to what said, once you add the %mend to the end of your macro function that will be the end of the macro definition, to actually run the macro you will have to invoke it, e.g.:

/* macro printit definition */

%macro printit;

proc print;

run;

%mend;

/* run macro printit */

%printit;
