SAVE cannot export an executable larger than 32MB (Win32)

Question 1

Version: 5.20 [build 3797]
Build date: 27 May 2021

In my extended vfxforth, the dictionary is set to 256MB. Once a program surpasses 32MB, SAVE throws an access violation. Both Claude AI and I confirmed. Claude says VFXSUPP.DLL has a hard cap of 32MB, even though the dictionary can be expanded without limit. This doesn't appear to be documented anywhere.

Frustrating.

Question 2

I'll have a look. I'm surprised that another client has not come across this as they often make executables larger than 30 Mb. Which version of Windows?
