ELOQUENCE B.08.20 - patch PE82-1809170

----------------------------------------------------------------------

This patch adds enhancements or fixes defects of the Eloquence IDE
for the Windows platform as released with Eloquence B.08.20.
This patch will be integrated in the Eloquence B.08.20 release.

Eloquence B.08.20 must be installed before applying this patch.

Severity:
 PE82-1809170: BUG FIX

Superseded patches:
 PE82-1712181: ENHANCEMENT
 PE82-1706220: ENHANCEMENT
 PE82-1605120: BUG FIX
 PE82-1510291: BUG FIX


Patch PE82-1809170
------------------

Platforms: Windows

* Fixed a text editor problem which could cause an internal
  memory corruption when a certain undo/redo sequence was
  issued. The Eloquence IDE would then terminate unexpectedly,
  either with a failed txtobj.cpp assertion or a segmentation
  fault.

  In this context, a previous fix of patch PE82-1510291 was
  removed. The original problem is now solved.

* Changed the Windows file version to "8.2.0.22"


Patch PE82-1712181
------------------

Platforms: Windows

* Fixed ambiguous syntax of the MAT "." operator (multiply array
  elements) and the member operator (#4260). The multiply operator
  was changed from "." to "#".

  As of B.08.20 the MAT statement supported operating on member
  variables. However this enhancement was in conflict with the "."
  operator that is used to multiply array elements.

    MAT A=B.C

  This could either mean copy the member array B.C or multiply the
  array elements from B and C.  As a consequence the "." operator
  was changed to "#" to resolve the ambiguity.

    MAT A=B.C    ! copy
    MAT A=B#C    ! multiplication

* Fixed internal error when using a STRUCT argument with a single
  line function (#4259).

  A STRUCT argument in a single line function resulted in an abort
  message similar to below:

  DEF FNA(STRUCT B)=1

  codegen.c:1299: cg_fix_expr: Assertion `cg == 1' failed.

* Changed the Windows file version to "8.2.0.21"


Patch PE82-1706220
------------------

Platforms: Windows

* The Server Configuration now supports multiple servers having
  the same name but different services.

* The "Text" Color Configuration category now defines the background
  color of the Text Editor window. Previously the Text Editor window
  background color was white, regardless of the Color Configuration.

* Changed the Windows file version to "8.2.0.20"


Patch PE82-1605120
------------------

Platforms: Windows

* Fixed a regression which under certain conditions could cause
  the IDE explorer to display a wrong file list after a file was
  saved.

  This problem was introduced with Eloquence B.07.10 IDE patch
  PE71-0710290 which enhanced the explorer to refresh its file
  list after a file was saved.

* Changed the Windows file version to "8.2.0.19"


Patch PE82-1510291
------------------

Platforms: Windows

* Fixed an unexpected behavior in space dependent parsing mode
  introduced with B.08.20 (#4200).

  As of B.08.20 the parser first attempts to parse a statement
  in space independent mode, regardless if space dependent mode
  is used. Only if this fails the space dependent mode is
  considered. This allows to resolve potential ambiguities in
  space dependent mode by using the correct case.
  This change could cause unexpected behavior as space characters
  might be ignored instead of being considered a delimiter.
  The parser was changed to treat spaces as delimiters if space
  dependent mode is used.

* This patch adapts to the new console window implementation as
  of eloqcore patch PE82-1507170 to solve eloqcore startup problems
  observed on Windows 10 Preview.

* Fixed a problem where under rare circumstances cutting or deleting
  a selection in the program editor could cause the IDE to abort with
  a message like below (#2546):

  Assertion failed: last_col <= line->Columns()
  File "txtobj.cpp", line 559

  Assertion failed: col <= data_columns
  File "txtobj.cpp", line 1289

* Fixed a problem where under rare circumstances opening the Find or
  Replace dialog in the program editor could cause the IDE to abort
  with a message like below (#4199):

  Assertion failed: !pMainFrame->m_pFindDlg
  File "editview.cpp", line 5186

* Fixed an internal error listing the statement MAT A.I=.I

  A message like below was output:

  Assertion failed: idx >= 0 && idx < l_stackp
  File "list.c", line 1497

* Changed the Windows file version to "8.2.0.18"
