In DOORS, how do I open up a file for writing? I understand and use this:
Stream out = write strFilename
The issue here is that I have a recursive script that needs to search through a directory(and subdirectories) for all of the modules below. I need to open each module, perform an action(write the actions data to a file), close the module and continue to the next module.
I wish to keep the file open until all data is written.
Is this possible?
Thank you for any help.

One possible solution could be to declare the Stream public, open the steam before the recursive function is called the first time, and close the steam after the first call returns. All you do in the recursive function is to write to the file.

Yes the Stream could be a global variable, opened for write once. You could also pass the Stream variable into all your functions. You could also open for write then close the stream at the start of your program which erases the file, then inside your recursive algorithm open the stream "append", write, then close, which will append the results.
1st and 2nd options will run quite a bit faster than continually appending the file.

Thank you for this feedback. I have searched the DXL help, and do not see exactly how I make a global variable(I am opting for the first two options).
Stream g_stOutput
// Global variable, not defined inside any function string NameSomeWindowsFile =
"c:/MyFolder/MyReports/MyRecursiveReport.txt"
void MyFunction(Object obj)
{ g_stOutput << number(obj)
"\t" identifier(obj)
"\n"
// Global variable used here
}
void MyRecursiveFunction(Object obj)
{ Object oChild MyFunction(obj)
for oChild in obj
do
{ MyRecursiveFunction(oChild)
}
}
void DoModule(Module mod)
{ Object oTop
for oTop in top(mod)
do
{ MyRecursiveFunction(oTop)
}
}
void ProcessFolder(Folder fld)
{ Item itm Module mod Skip skpItems = createString()
// used to put items alphabetically sorted
// [1] Get items in the folder
for itm in fld
do
{
if (!isDeleted(itm)) put(skpItems, name(itm), itm)
}
// [2] process modules in the folder
for itm in skpItems
do
{
if (type(itm) ==
"Formal")
{ mod = read(fullName(itm), false,
true) DoModule(mod) close(mod)
}
}
// [3] recurse sub-folders and projects
for itm in skpItems
do
{
if (type(itm) ==
"Folder" or type(itm) ==
"Project") ProcessFolder(folder(fullName(itm)))
} delete(skpItems)
}
void DoFolder(Folder fld)
{ g_stOutput = write(NameSomeWindowsFile) ProcessFolder(fld) close(g_stOutput) system(
"Notepad.exe " NameSomeWindowsFile)
} DoFolder(current Folder)
