Severity:
 PE83-1909100: BUG FIX, ENHANCEMENT

Superseded patches:
 PE83-1906060: BUG FIX
 PE83-1905030: BUG FIX
 PE83-1904160: BUG FIX


Patch PE83-1909100
------------------

Platforms: All

* Fixed unexpected abort when accessing a TYPE variable after STOP
  (#4294). A message like below was issued:

  Internal error processing line 0
  Assertion failed: (cls->magic == 0x434c5344)
  file class.c, line 534 in function get_class_ptr

* Specifying a return variable for a DLG LOAD statement could have
  no effect (for example: DLG LOAD Filename$;Status).

  On DLG LOAD failure, a runtime error could be issued unexpectedly
  instead of assigning the error code to the return variable.

* Fixed wrong character conversion when using an Unicode \u escape
  sequence in a DLG file (#4299).

* Improved DLG v2 enhanced diagnostics and error handling (#4298).

  DLG GET ".status",Stat
  DLG GET ".status_msg",Msg$
  DLG GET ".status_seg",Seg$
  DLG GET ".status_file",File$
  DLG GET ".status_line",Line

  These statements now synchronize any DLG calls still pending in
  DLG v2 bulk mode. Previously, they could be invoked only after
  a DLG status had been issued (for example in an ON ERROR handler).
  Now they can be used anytime to make sure any pending DLG calls
  have been processed.


Patch PE83-1906060
------------------

Platforms: All

* Fixed DLG GET ComboBox.line[] unexpectedly resulting in ERROR 660,
  caused by incomplete attribute cache implementation (#4290).

  Please note that this fix requires JDLG version 2.0.3 or newer,
  available for download at:
  https://eloquence.marxmeier.com/download/jdlg/2.0/

* Fixed IPv6 addresses not recognized in -dlg command line option
  and DLG SET ".driver" statement.

  IPv6 addresses are now recognized in square brackets, for example:
  eloqcore -dlg [fe80::4261:86ff:feee:9437]
  DLG SET ".driver","[fe80::4261:86ff:feee:9427]:12345"


Patch PE83-1905030
------------------

Platforms: All

* Fixed a problem where POPUP BOX could unexpectedly return error 870
  (Improper POPUP BOX format) if the definition is passed in a string
  variable, caused by an incorrect string length calculation.

* Fixed incomplete DLG GET "Tree.udata[I]" result, caused by incorrect
  string length calculation if cached attribute values are returned.

* Fixed possible crash when obtaining enhanced DLG v2 diagnostics, for
  example DLG GET ".status_msg". A message like below was output:

  Assertion failed: (seg->magic == 0x5345474d)

* Fixed unexpected asynchronous execution of certain DLG SET statements.
  The statements below are now synchonously executed:

  DLG SET "Application.browser"
  DLG SET "Application.closeprinter"
  DLG SET "Application.openprinter"
  DLG SET "Application.print"
  DLG SET "Dialog.do"
  DLG SET "System.activate"
  DLG SET "System.sound"
  DLG SET "System.start"


Patch PE83-1904160
------------------

Platforms: All

* Fixed error 653 on DLG SET when using utf-8 encoding.

  The DLG functionality may internally use the multi-byte utf-8
  encoding where the number of bytes and characters may differ.
  The max. length of a text field (.maxchars attribute) was compared
  against the number of bytes instead the number of characters.
