This command allows you to return a section of memory reserved by GRAB to QDOS.
LOAD, CLEAR, NEW and similar commands do not free GRABbed memory (unlike memory reserved with ALCHP).
Never free memory where extensions, device drivers or other code have been loaded and started (for example with CALL) because the operating system will continue to update these routines regularly and find code which may have been overwritten by other programs, internal data etc. Crash!
RELEASE activates the enhanced sound capabilities of the ST/QL (or the QSound interface which has now been out of production for some years). A sequence which has been previously stored with PLAY under the number nr is ‘executed’ by RELEASE.
