Hi Daniel,

That plist stuff should not be a messy problem. I am SURE there are others who could provide an even more simplified approach, but I have found this to work...

First, put your info into a dictionary and send it to a routine like this...

- (OSErr) WriteInfoToFile:(CFPropertyListRef)theXMLInfo
forFile:(NSString*)filename
{
OSErr theErr = noErr;

CFDataRef theXMLData = CFPropertyListCreateXMLData(NULL, theXMLInfo);
CFIndex theXMLSize = CFDataGetLength(theXMLData);

if(0 < theXMLSize)
{
FILE *theFile = NULL;
char* cstr = (char*)[filename cString];

theErr = <FILE_PerformOpen>(&theFile, cstr, kForWrite);
if((noErr == theErr) && (0 != theFile))
{
<FILE_PerformWrite>(theFile, (UInt8*)CFDataGetBytePtr(theXMLData), theXMLSize);
<FILE_PerformClose>(theFile);
}
}
else
{
theErr = kWhateverErrorYouWantToReturn;
}

return(theErr);
}

// ---------------------------------------------------------

Later, you could read it in...

CFPropertyListRef localPlist;
CFDataRef cfData;
UInt8 *buffer;
CFIndex fileSize;

OPEN FILE
LEARN FILE SIZE
CREATE BUFFER OF FILE SIZE
READ INTO BUFFER
CLOSE FILE

cfData = CFDataCreate(NULL, buffer, fileSize);
if(NULL != cfData)
localPlist = CFPropertyListCreateFromXMLData(NULL, cfData, kCFPropertyListImmutable, nil);

Then calls like "keyCFString = (CFStringRef)CFDictionaryGetValue(localPlist, valueString);"
would return whatever particular item it was you were looking for.
