4. DEFINITICNS OF TERMS

These definitions, when in lower case, are terms used within this Standard.

They present tenns as specifically used within FORI'H.

A

address, byte

An unsigned number that locates an 8-bit byte in a standard FOR'll! ,; address space over { 0 •• 65, 535 } • It may be a native machine address or a representation on a virtual machine; locating the 'addr-th' yte within the virtual byte address space. Address arithmetic is modul.o 65, 536 without overflow.

address, compilation

The numerical value equivalent to a FORTH word definition, which is compi.Led for that definition. The ddress interpreter uses this value to locate the machine cede corresponding to each definition. (May al. o be called the code field address. )

address, native �chine

The natural address representation of the host computer.

address, parameter field

The address of the first byte of mencry associated with a word definition for the storage of compilation addresses (in a colon-definition), numeric data and text characters. arithmetic All integer arithmetic is performed with signed 16 or 32 bit two's complement results, unless noted.

B

block

The unit of data from mass storage, referenced by block number. A block must contain 1024 bytes regardless of the minimum data unit read/written from mass storage. The translation from block number to device and physical reC'Ord is a function of the implementation.

block buffer

A menory area where a mass storage block is maintained.

byte

An assembly of 8 bi ts. In reference to mencry, it is the storage capa.ci ty for 8 bits.
