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*/
