▄ Mem, MemL, and MemW
Borland Pascal implements three predefined arrays to directly access memory: Mem, MemL, and MemW.
■ Each component of Mem is a Byte
■ Each component of MemW is a Word
■ Each component of MemL is a Longint.
The Mem arrays use a special syntax for indexes: two expressions of the Integer-type Word, separated by a colon, specify the segment base and offset of the memory location to access.
