NOLAXNESTED behavior modification

The NOLAXNESTED compiler option should just prevent code in a proc and nested procs to be intermixed.
The rule should be that the code in a proc forms a single 'block'.

Case 1 : All nested procs AFTER the code => Acceptable

 

    a: proc;

      dcl (x,y,z) fixed bin;

      x = 1;

      y = 2;

      z = 3;

      b: proc;

      end b;

      c: proc;

      end c;

    end a;             

 

 

Case 2 : All nested procs BEFORE the code => Acceptable

 

    a: proc;

      dcl (x,y,z) fixed bin;

      b: proc;

      end b;

      c: proc;

      end c;

      x = 1;

      y = 2;

      z = 3;

    end a;             

 

Case 3 : All nested procs BEFORE or AFTER the code (which is still a single block) => Acceptable

 

    a: proc;

      dcl (x,y,z) fixed bin;

      b: proc;

      end b;

      x = 1;

      y = 2;

      z = 3;

      c: proc;

      end c;

    end a;             

 

Case 4: Code is not a single ‘block’ => Not acceptable under NOLAXNESTED

 

    a: proc;

      dcl (x,y,z) fixed bin;

      x = 1;

      b: proc;

      end b;

      y = 2; => Should be flagged

      c: proc;

      end c;

      z = 3; => Should be flagged

    end a;             

 

Instead of flagging each statement individually, the 'block' should be flagged as a whole (to avoid a long list of identical messages if the 'block' contains lots of statements).

    This will flag code unless all the subprocedures come either before or all after the code
