After Installing

For applications created with earlier Micro Focus products, note the following:

Application Workflow Manager

There are significant structural changes to Application Worklflow Manager (AWM) and to z/Server in Enterprise Developer 2.3. See Backward Compatibility of AWM Models for details about how this affects existing AWM models.

Existing Applications

Application executables that were compiled using earlier Micro Focus products must be recompiled from the sources using Enterprise Developer. For more information, read the section Upgrading to Enterprise Developer for Eclipse in the product Help.

Open PL/I Compiler

Important: If you are installing this release as an upgrade to Enterprise Developer 2.2 Update 1, after the upgrade you must rebuild any applications that are compiled using the –zp1 option.

The behavior of the –zp1 option has been reverted to that of versions of Enterprise Developer earlier than 2.2 Update 1, with an additional correction relating to Char Varying data items.

The behavior has been restored to that in Enterprise Developer versions earlier than 2.2 where, when compiling with –zp1, all parameters are treated as unaligned. (In Enterprise Developer 2.2 Update 1, the behavior when compiling with –zp1 was to not treat parameters as if unaligned).

When using the –zp1 compiler option, all Character Varying data items are now treated as if unaligned. In previous versions of Open PL/I, for Character Varying data items, the –zp1 unaligned requirement was applied only to structure members and parameters.

To illustrate the change, consider the following example:

zptest: proc options(main); 
 
   dcl 1 st1, 
     2 c char, 
     2 x(4) char(7) var init ('a', 'xx', 'yyy', 'zzzz'); 
 
   dcl y(4) char(7) var init ('a', 'xx', 'yyy', 'zzzz'); 
 
   dcl sub entry ((4) char(7) var); 
 
   call sub (x); 
 
   call sub (y); 
 
end; 
 
sub: proc (z); 
 
   dcl z(4) char(7) var; 
 
   dcl i fixed bin(31); 
 
  do i = 1 to hbound(z); 
      z(i)  = 'x'; 
  end; 
 
end; 

Where:

• For x and z, each char (7) var item is 7 plus 2 bytes which equals 9 and then multiplied by 4 equals 36.
• If y were aligned on half-word by default, each array element is half-word aligned and each equals 10 bytes (9 + 1 pad byte), and the total size equals 40 bytes.
• At call sub (x), the calling argument and parameter are matched.
• At the call sub (y), the y element size (10 bytes) is mismatched against the parameter z element size (9 bytes) due to –zp1. This is incorrect and causes unexpected program behavior.

Due to this correction of treating all Char Varying data items as if unaligned when using –zp1, the size of CHAR VARYING arrays now differs from previous versions of Open-PL/I. For example:

   dcl X(4) char(7) var; 
 
   Put skip list (size(X))  /* size is 36 bytes vs. 40 bytes in previous versions of Open-PL1 */
