IBM 1401 Symbolic Programming Systems: SPS-1 and SPS-2
Specifications and Operating Procedures
This manual provides programmers with the informa-
tion necessary to code a 1401 program in SPS language
and assemble a machine-language object-program. It is
assumed that the programmer has a basic knowledge
of 1401 machine language programming.
It describes symbolic programming principles and
concepts and gives detailed speCifications of the 1401
Symbolic Programming Systems, SPS 1 and SPS 2.
Operating instructions for processing the SPS source
program are enumerated. The SPS processor program
can assemble a machine language program on configu-
rations of the 1401 Data Processing System equipped
with a 1402 Card Read-Punch.
A sample program is included for the convenience
of the beginning SPS programmer. Input and output
forms, a block diagram of the program procedure, the
symbolic program, and SPS output listings of the sym-
bolic and machine-language programs are shown.
