Or you can drop this into your code above the call:

%macro left(text);
%****************************************************************;
%* MACRO: LEFT                                                  *;
%* USAGE: 1) %left(argument)                                    *;
%*                                                              *;
%* DESCRIPTION:                                                 *;
%*   This macro returns the argument passed to it without any   *;
%*   leading blanks in an unquoted form. The syntax for its use *;
%*   is similar to that of native macro functions.              *;
%*                                                              *;
%*   Eg. %let macvar=%left(&argtext)                            *;
%*                                                              *;
%* NOTES:                                                       *;
%*   The %VERIFY macro is used to determine the first non-blank *;
%*   character position.                                        *;
%****************************************************************;
%local i;
%if %length(&text)=0 %then %let text=%str( );
%let i=%verify(&text,%str( ));
%if &i %then %substr(&text,&i);
%mend;

Subject: warning message for %left

hello.

i just tried to run some old code that used to run cleanly. however, now, i
get the following warning:

WARNING: Apparent invocation of macro LEFT not resolved.

this problem causes bigger problems further on.

any thoughts?

many thanks.
