answer from en.wikipedia.org
Block Started by Symbol (BSS) was a pseudo-op in UA-SAP (United Aircraft Symbolic Assembly Program), the assembler developed in the mid-1950's for the IBM 704 by Roy Nutt, Walter Ramshaw, and others at United Aircraft Corporation. This pseudo-op was later incorporated into FAP (FORTRAN Assembly Program), the standard IBM assembler for the IBM 709, 7090 and 7094 computers. It defined its label and reserved space for a given number of words.
Most modern assemblers produce a BSS section in their output object module containing all reserved but uninitialized space. |
