#184 (Bug, 2018-03-21): HYPERLINK ignored in RTF import
Some RTF exporters add leading white space to the HYPERLINK field instruction.
This leading white space needs to be skipped in order to handle the HYPERLINK correctly.
In addition, the closing double quote of the link target needs to be removed.
This applies to all HYPERLINKs.

#186 (Bug, 2018-06-02): aligning code procedure syntax with docu
Dev/Docu/P-S-I.odc specifies that code procedures are a comma-separated sequence of constant expressions.
Leading, trailing, or multiple adjacent commas are not allowed.
In addition, the docu allows arbitrary constant expressions, not only integer and string literals.
The parser in DevCPP.GetCode therefore needs to be aligned with the docu.
Reported by Zorko, 2018-04-18.
#187 (Feature, 2018-06-07): adding a run-time debugger to BlackBox
It is proposed to add a run-time debugger for BlackBox.
A prototype of such a debugger is available from Oberon microsystems
and has been adapted to BlackBox 1.7 by oberoncore.
It is based on the Windows debugging API and is able to set code
and data breakpoints, do single step execution and more.
However, the user interface needs improvements and various changes
made in the post-mortem debugger since BlackBox 1.6 need to be applied
also to the run-time debugger.
Proposed by J. Templ, 2018-05-15.
#188 (Bug, 2018-06-16): compiler trap with SYSTEM.VAL
The following example leads to a compiler trap:
<pre>
PROCEDURE Test;
VAR li: LONGINT; s: SET;
BEGIN
li := SYSTEM.VAL(LONGINT, s * s) + 1
END Test;
</pre>
Reported by Oleg N. Cher, 2018-06-12.
#189 (Feature, 2018-07-05): improving the treatment of the sign bit in Math/SMath
It is proposed to add the functions CopySign and SignBit according to IEEE 754-2008 to Math/SMath. In addition, the implementation of Sign, Sinh, Tanh, ArcSinh, ArcTanh, Mantissa, and Real should return negative zero (-0.0) if the argument is negative zero.
Reported by Robert, 2018-06-19.
#190 (Documentation, 2018-11-30): add comment about stack and heap memory configuration
When increasing the stack size in DevLinker for creating an exe file with a larger stack the
heap size must be reduced. Otherwise there may be strange effects for example when opening
a file dialog box because Windows functions are running out of memory.
This fact should be added as a comment in Kernel and DevLinker.
#191 (Bug, 2018-11-30): fixing a compiler trap after syntax error
The compiler produces a NIL dereference (read) trap instead of an error message
for the following example:
@MODULE TestCompilerError;
VAR string: POINTER TO ARRAY OF CHAR;
BEGIN NEW(string, LEN 5 1); ...

#192 (Bug, 2018-12-07): Kernel.Call does not work with ANYREC-parameters
Kernel.Call does not work with ANYREC-parameters because the type tag is not passed.
Reported by Eugene Temirgaleev.
#193 (Bug, 2018-12-10): typing error in Documents.SetPageOp.Do
In the procedure Documents.SetPageOp.Do a typing error should be fixed.
wrong is:
op.ph := d.ph;
correct is:
op.pw := pw;
Reported by Ivan Denisov
#194 (Bug, 2018-12-20): Meta.PutParam and Kernel.Call for open arrays are mismatched
Meta.PutParam and Kernel.Call for open arrays are mismatched.
Thereby the order of parameters representing the length-vector
of a multi-dimensional dynamic array gets inverted.
Reported by Eugene Temirgaleev, 2018-12-02.
#195 (Bug, 2018-12-20): support for long identifiers in trap handlers
issue-#36 introduced long identifiers for CP names but the
procedure GetTrapMsg in DevDebug and StdDebug trap when using them.
Reported by Helmut Zinn, 2018-12-01.
#196 (Feature, 2019-02-18): StdCoder to support both "\" & "/" in file paths
Currently StdCoder only supports "/" as a file path separator, whereas most other BlackBox routines support both "\" & "/".
The proposal is to also support "\".
An implementation has been proposed by luowy (see https://forum.blackboxframework.org/viewtopic.php?f=40&t=748).
Reported by luowy.
#199 (Bug, 2019-07-01): compiler trap with SYSTEM.ADR(BasicType)
The following erroneous module causes a compiler trap because it tries to access the type descriptor of a basic type, which does not exist.
@MODULE TestAdr;
IMPORT SYSTEM;
PROCEDURE Adr;
BEGIN ASSERT(~ODD(SYSTEM.ADR(INTEGER)));
END Adr;
END TestAdr.

#200 (Bug, 2019-07-09): network file delete under Win10 sometimes fails
Under Windows 10 it has been observed that deleting a file on a network share sometimes
does not work. This is possibly related to using a virus scanner. However, repeating the
delete attempt does work and this leads to the proposed change appended below.
