Thus, —99 would be 100000000000000000000000000001100011 The numbers in the memory are actually represented in binary; however, in 2 · 3 BINARY NOTATION 45 describing these numbers it is more convenient to use octal notation. The transformation from octal to binary is so simple that the octal description does not obscure any essential facts. The representation of the decimal numbers 99 and — 99 in the memory can be written 000000000143 and 400000000143 in octal.

IBJOB has two sets of tables that define the correspondence between the Fortran unit number and the physical unit. In the first table, the standard units receive a standard name. The name, SYSINl denotes the standard system input tape. SYSPPl denotes the standard punch tape; SYSUT1 denotes a utility tape: this tape can be used for any purpose. The first IBJOB table might contain the following information: Fortran unit 1 equals SYSUT1 ; it is to be used for binary information and the maximum size of any records is 256 words.
