Hello Stephen,

If I want to save my application, about 800mb,  to an .exe with then command "SAVE" it's give an error "outside dictionary".

In a test, I rename the command "ALLOT" in :   : allot drop 1000 ;

SAVE now works, but of course it's not a working programm anymore.

Seems to me to be a memory issue, and do you have any idea to solve this?

with regards,

Hugo Overbeek

SAVE operates on the current dictionary, which has to be less than the stated maximum dictionary size.

1024 Mb set-size
save bigvfx

run bigvfx
compile app
save app

some attempts:

first I made bigvfx

Try the 64 bit versions from

https://vfxforth.com/downloads/VfxCommunity/

The fault is likely to be in the 32 bit memory allocator - we just use one of the system ones.

I try the 64bit version for windows and did a small test

 Free dictionary = 6719494 bytes [6562kb]


10 mb set-size  ok
save VFXbig10
adding extension
saving VFXbig10.exe ok


close current and try to execute VFXbig10

windows show's a remark:
"this app can't run on your pc"
"to find a version for your PC, check with the software publisher"

Did this on two pc's both with the same remark.

Any idea?

The app needs code signing - you are getting a blue box, I think. Until we reissue a code signed version, you can allocate 800 MB of memory using ALLOCATE or PROTALLOC

800 mb protalloc value mem
$C3 mem c!     \ return opcode
mem execute  \ test

works for me on Windows 11. You will probably need a huge data file, but it'll work. If you need a fixed address, Google mmap() for Windows. See VirtualAlloc()

When can we expect to have a code-signed version?
