No there is no limit on size of package or model other than
a practical memory limit. By that I mean at some point the model can get
so large, that it starts using virtual memory, and things can become
slow.
As a quick size example here is a script that creates 3 packages, each with
a 1000 classes in it.
Sub Main
Dim cat As category
Dim cls As class
For x = 1 To 3
Set cat = roseapp.currentmodel.rootcategory.addcategory("cat" & x)
For y = 1 to 1000
Set cls = cat.addclass ("class_" & x & "_" & y)
Next y
Next x
MsgBox "DONE"
End Sub
More than likely what you are actually running up against is
a limit within the scripting language. You are probably doing some
recursive call that is using up all of the stack space.
If this is the problem you are encountering (and it usually happens
in the 200-400 range of some repeated operation, so it sure sounds
like it), here are some additional notes on the subject that hopefully
will help:
------------------------------------------------------------------
Script returns an error, 'Out of Stack space'
------------------------------------------------------------------
Most likely caused by recursion in the code.
Rose Script has a maximum stack of 8k (which we have it set to).
This is the maximum you can have with Summit Basic (the language
we license in Rose). One of Rational's developers wrote to Summit
Basic regarding this problem with another script, here is their
reply.
--------------------- start of mail message ---------------
Yes, you have exceeded stack space. When you Dim a userdialog, the
entire dialog definition is allocated on the execution stack, of
which there is 2K by default (but you can increase to a miximum of
8K).
To work around the stack limitation, you need to place the dialog
declarations into subroutines.
--------------------- end of mail message ---------------------
Scripts invoked using the RoseScript option on a menu or started
by RoseApp.ExecuteScript appear to have very limited stack. The
same scripts run in the script debugger have considerably more.
Why is this?
Running compiled scripts from the menu eats up more stack space then
running source in scripting environment, which has a larger amount of
stack space, hence it will often work when run directly but not from
the menu. If you run the script in the debug window the bounds are not
as tight as when running the compiled version. Much the same as when
running a debug version of C++ code and a release version of C++ code.
The debug environment is not as strict at times.
------------------------------------------------------------------
POSSIBLE WORKAROUNDs:
------------------------------------------------------------------
1) Some Code needs to be rewritten to avoid the deep recursion in
the program.
2) Not a fix but a way to get further along is to increase stack
space by running the file as a .ebs as oppossed to .ebx from
menu. This will get you 2 or 3 times further before hitting stack
limit as oppossed to if you run the ebx file directly. There maybe
some other speed issues since you are now running .ebs, but that's
the trade off.
3) Put parts of the script in a VB component and use it from the script.
You may want to rearchitect the integration by extracting some
of the logic and placing it in a COM client to Rose since this is
the most scalable solution.
4)
Fully port to visual Basic
You have the option of creating an Addin or script with VB and porting
the Rose Script code to VB.
------------------------------------------------------------------
PROBLEM EXAMPLES:
------------------------------------------------------------------
1)
Sub recurse (ByVal depth As Integer)
Print depth
recurse depth+1
End Sub
Sub Main
viewport.open
recurse 1
End Sub
runs for 359 iterations in the debugger before stopping with an out of
stack space error.
If started from the menu it recurses 80 times before stopping (with no
error message). Whilst the example is trivial some of my more complex
scripts now won't run from the menu
------------------------------------------------------------------
2)
The following script compiles and runs if executed directly (.ebs).
Script fails to execute if compiled ebx is run.
If ANY two lines are removed from dialog, then compiled script runs.
Fails in both Rose 98 and Rose 98i.

Subject: (ROSE) How many classes can you load into a package ?
Hi,
for a dictionary of terms I tried to load all my terms as classes in a
package
called "terms a-z". When my script reached number 230, the load broke. Does
anybody know a solution? Or is the capacity of a package restricted to 230
classes?
Thanks in forward,
Sincerely
Heinz
