APAR status

• Closed as program error.

Error description

• When using a preprocessor for PL/I source it may result in
  errors for expanded source.
  
  Example:
  
  Before running preprocessor:
  
           GET $VALUE FROM  ACCNT
                     WITH  PURGE
                     USING ACCNT_NAM;
  
  Expanded source after running processor:
  
  /*                                                       **ME**
          GET $VALUE FROM  ACCNT
                    WITH  PURGE
                    USING ACCNT_NAM;
  */                                                       /*ME*/
  CALL BNK1('@XC$$' || '0001112222333DA8F020'X,           /*ME*/
            'BOND1',                                      /*ME*/
            CHK,                                           /*ME*/
            SAVI,                                           /*ME*/
            'EXTRACT-TOTAL             ',             /*ME*/
            $VALUE                            ,             /*ME*/
  
  
  Example of error messages that may be seen:
  
  Preprocessor statement resolution contains the following error:
  "/*" is invalid.
  
  Multiple markers at this line
    - Preprocessor statement resolution contains the following
  error: "ERROR_TOKEN" unexpected tokens ignored
    - Preprocessor statement resolution contains the following
  error: "=" expected instead of this input.
  

Local fix

• Modify the preprocessor to create a single delta for each
  preprocessor change, for example:
  
  Before running preprocessor:
  
           GET $VALUE FROM  ACCNT
                     WITH  PURGE
                     USING ACCNT_NAM;
  
  Expanded source after running processor:
  
  /*                                                       **ME**
  *        GET $VALUE FROM  ACCNT
  *                 WITH  PURGE
  *                 USING ACCNT_NAM;
  */                                                       /*ME*/
  CALL BNK1('@XC$$' || '0001112222333DA8F020'X,           /*ME*/
            'BOND1',                                      /*ME*/
            CHK,                                           /*ME*/
            SAVI,                                           /*ME*/
            'EXTRACT-TOTAL             ',             /*ME*/
            $VALUE                            ,             /*ME*/
