FREE_FAST

Syntax FREE_FAST
Location ATARI_REXT for QVME (v2.31+)

The Atari TT recognises two types of RAM, standard ST RAM (up to 10MB) and FastRAM (otherwise known as TT RAM) which is specifically designed for the Atari TT and works about twice as fast as the standard ST RAM.

The QL emulator can use both types of RAM but will only recognise and use a maximum 4MB of standard ST RAM.

If FastRAM is available, the Emulator places the device drivers into this area in order to speed them up as well as freeing additional standard ST RAM. However, if your programs are to access the FastRAM, they need to use various new commands. FREE_FAST is a function which returns the amount of available FastRAM.

CROSS-REFERENCE

The other commands to access FastRAM are RESFAST, and LRESFAST.

Compare RESPR, ALCHP and FREE_MEM.
