Syntax Description

SERROR

issues a warning message when a macro variable reference does not match a defined macro variable.

NOSERROR

does not issue the SAS system warning messages when a defined macro variable reference does not match a macro variable.

CAUTION:

When you develop and test programs, the SERROR setting is more useful to you than the NOSERROR setting.   

Details

Several conditions can occur that cause a macro variable reference to go unmatched with an appropriate macro variable. These conditions appear when

• the name in a macro variable reference is misspelled

• the variable is referenced before it has been defined

• the program contains an ampersand (&) that is followed by a string, without intervening blanks between the ampersand and the string.

  For example, this statement uses an ampersand as the symbol for the logical operator AND with no intervening blanks:

  if x&y then do;

• the program contains an ampersand (&) that is used as a literal and is enclosed in double quotation marks:

  if buyer="Smith&Jones, Inc." then do;
