Announcing Synergy/DE for .NET Beta Release
Gives Synergy developers a fully integrated .NET language
We are very pleased to announce the release of Synergy/DE for .NET beta 1!
Synergy/DE for .NET gives Synergy developers a fully integrated .NET language, which provides:
• The ability to call Synergy routines from other .NET languages and call other language
routines from Synergy Language
• Native IL code generation
• Support for inherent multi-threading in the .NET Framework
• Support for calls to virtually all .NET Framework features
• Support for Visual Studio features:
o Native debugger step-through from one language to another
o Hover over to see a variable’s value
o Full IntelliSense and colorization
o Code snippets
o Code regions
Synergy/DE for .NET beta 1 supports WPF, Windows Forms, console, and class library projects, as well as the most common Synergy Language system subroutines and functions. Future releases will support xfNetLink projects, additional system subroutines and functions, and other features. Beta 1 was shipped to testers last week as a VMware virtual image on USB flash drives. Beta testers will run existing code through the new Synergy/DE for .NET environment and also develop new Synergy code in Visual Studio .NET. If you would like more information about the Synergy/DE for .NET beta program, please let us know. |

“Data Model” Not the Same as “Date a model”…But Still Pretty Cool
By Tod Phillips, PSG Consultant, Synergy/DE
When I was first approached about testing the Synergy/DE Data Provider for .NET, which enables ADO.NET Entity Framework (EF) access to Synergy databases, I remember thinking that I had too much on my plate already and that testing would have to wait. But when I heard that using the data provider and the EF would allow me to date a model, I suddenly got interested and agreed to dive into it immediately.
It didn’t take long to figure out that I would not, in fact, be heading out for a night on the town with a cover girl. By then, I’d read enough to know that Entity Data Models are at the heart of the Entity Framework, and not a bunch of gorgeous blondes and brunettes. My wife was ecstatic.
I rather sullenly got to work and began my research. I quickly learned that the Synergy/DE Data Provider for .NET wraps the native ODBC data provider, and that it provides Entity Framework access to Synergy data. The EF, in turn, provides a new method for accessing and dealing with data by the use of constructs known as Entity Data Models.

Synergy/DE Tech Tip
Using %NUMARGS and trailing null arguments
In a previous tech tip, we saw how using mySub() resulted in %NUMARGS returning a value of 1. As a Synergy programmer, you can determine the number of parameters you’re passing to a subroutine/function by counting the number of commas between the parentheses and adding one, bearing in mind that no parentheses = no parameters.
You can change the behavior of %NUMARGS by using the “trim” compiler option (–T on Windows/Unix or /TRIM on OpenVMS). This option will remove all trailing null (i.e., not passed) arguments. This will also have the effect of %NUMARGS returning 0 for mySub() .
The program below demonstrates the behavior of %NUMARGS.
.main
proc
open(1,o, 'TT:')
xcall argcount
xcall argcount()
xcall argcount(1)
xcall argcount(2,1)
xcall argcount(3,,)
xcall argcount(4,,1,)
xcall argcount(,,,,)
stop
endmain
subroutine argcount, varargs
proc
writes(1, %string(%numargs))
return
endsubroutine
When compiled without using –T, the program output is
0
1
2
3
4
5
When compiled with –T, the program output is
0
0
1
2
1
3
0
If you are using the default compiler options in Workbench, you have the –T option already set, as it’s required when using the ActiveX API. However, you should check the use of /TRIM on OpenVMS, especially with any source that uses system service routines.
So, if you’re using %NUMARGS, you really should use it in conjunction with ^PASSED, so that you don’t try to process null arguments. Note that XCALLing a non-^VAL function can also affect the routine parameters and change the value that is reported by %NUMARGS. |

Quiz
Synergy/DE pros, see if you can answer this question!
Given the following class:
class sample
public method sample
in req other, @sample
proc
;;do something with other
end
public method sample
proc
end
endclass
If we change the type of the constructor parameter “other” to “@*” (object), what do we need to recompile?
a. Nothing, because @* is an ancestor class to @sample
b. Just this source file
c. Any source file containing code that uses that form of the constructor
d. Any source file that makes any reference to the class sample
e. Oh heck, just rebuild everything!
