PI85359: IDZ / RDZ REAL TIME SYNTAX CHECK SHOWS ERRORS FOR EXCLAMATION POINT CHARACTER

APAR status

• Closed as program error.

Error description

• IBM / Rational Developer for z Systems real time syntax check
  shows errors for Exclamation point character
  
  This is when there are multiple *PROCESS statements and *PROCESS
  OR('!') is not the first *PROCESS statement
  
  PL/I parser is only handling the first *PROCESS statement in a
  program
  
  Errors shown are:
  Multiple markers at this line
  - Unexpected character Ignored
  - "ERROR TOKEN" unexpected tokens ignored
  and
  - "P1InfixOperators" is invalid
  
  ************* SOURCE START ****************
  *PROCESS MARGINS(1,100) MACRO;
  *PROCESS SOURCE XREF;
  *PROCESS NOT('ªˆ') DFT(BYVALUE)  ;
  *PROCESS OR('!');
  
  INFIX1: PROC() OPTIONS(MAIN);
  
  DCL AA CHAR(10);
  DCL BB CHAR(10);
  DCL CC CHAR(10);
  DCL DD CHAR(10);
  DCL CONCAT3 CHAR(20);
  
  Dcl 1 Test,
      3 Field1 char(10) ;
  AA = ' ';
  BB = ' ';
  CC = ' ';
  DD = ' ';
  
  /* Errors are shown at next 2 statements */
  IF AA > BB ! CC > DD THEN DISPLAY ('Z');
  Concat3 = 'HEL' !! 'LO';
  END INFIX1
  *************  SOURCE END   ***************
  

Local fix

• Move the following statement *PROCESS OR('!'); to the top of the
  *PROCESS statements);
  

Problem summary

• If the left margin is set to column 1 by a compiler option or
  *PROCESS statement, the IDz PL/I parser ignores subsequent
  *PROCESS statements.
  

Problem conclusion

• Modified the PL/I parser to correctly handle *PROCESS
  statements, regardless of MARGINS values.
  

Temporary fix
