Under Win98 the Win32 Edit control used by Win32::GUI::Textfield is 
limited to about 32K bytes;  It can be increased to (about?) 64K bytes 
using the SetLimitText() method.

Under WinNT/2K/XP I can't find the default limit documented (it may be 
the same, but you can look using the GetLimitText() method). I think 
under these OS's it should be possible to increase the allowed size with 
SetLimitText() to several megabytes - Sorry, but I don't have a suitable 
machine at hand to try.

If you want more space than this, the try using the RichEdit class - it 
should be (almost) a drop in replacement for the Textfield, and IIRC the 
text limit can be increased to about 2GB.
