SUBROUTINES, SERVICE ROUTINES AND BRIDGE II
Subroutines
Subroutines a r e designed to handle, manipulate, move, o r s o r t information within the computer
memory. Some of the important routines accomplish the following:
a
Conversion of data from one radix to another (octal, binary; BCD)
a
Word replacement
a
Internal memory s o r t
To solve problems in scientific a r e a s , mathematical routines a r e available to calculate complex
functions and mathematical procedures such as:
Sine-cosine, square root, arctangent, exponential, and logarithm
Matrix transposition, inversion
a
Scalar multiplication
a
Linear simultaneous equations
a
Multiple regression
a
Roots of a polynomial
a
Least squares polynomial fit
a
Linear programming
Service Routines
The main functions of service routines a r e to assist in debugging programs and in simplifying oper-
ating procedures.
These routines have been prepared in symbolic and/or object program form.
Service routines to perform tasks such a s the following a r e available:
a
Reset memory
Dump memory to cards, magnetic tape, paper tape, o r printer
a
Load programs into memory
a
Trace programs
a
Compare, correct, and print out contents of tape
a
Correct c a r d s
