Use The purpose of this call is to return an aligned area of free RMA claimed for use. h4. Notes The block address returned in R2 will satisfy (R2 MOD R4)=0. This is in contrast to [[OS_Module 6]], which always returns an address (R2 MOD 16)=4. If an aligned block is resized via [[OS_Module 13]] then it is not guaranteed to remain aligned. This call was introduced in RISC OS 5.27. h4. See also * [[OS_Module]] * [[OS_Module 6]]
