Version:
KERNEL: v0.4.0-alpha+333 (2021-08-07)
BASIC VERSION: BASIC816 v0.2.0-alpha+411
HARDWARE: Foenix U

Description:
When a BASIC program reaches a size of more than 16K and is saved (on any device) the machine locks up and shows the following number (address?):

1A45E1

You can use the attached file to demonstrate the issue in the following way:

• Unzip & Load the Attached file SPRED41.ZIP
• Add the following lines of code (tried to keep it to a minimum)

Code:

6100 rem change background color - blue component
6110 bkg%=&haf000d
6120 poke bkg%,colb%
6130 spriteat 7,sx%*4+colb%+32,sy%*44+32
6140 goto 500

• Try to save the file with any name
• The file won't save & the computer will lock up showing the stated number (Error Code / memory address?)

Are you able to LIST the file when it's that big?

[econtrerasd]

Yes I can list it, It actually runs perfectly, but when you save it it's when the problem arises.

Thanks. The way SAVE works is essentially by LISTing to a memory buffer and then saving the contents of the buffer to the file system. So that suggests either a problem with how the buffer is managed or with the way the kernel saves the memory.
