General Assembly Program 3 is used to convert punched cards or magnetic tape to punched
paper tape and will punch paper tape in either of two formats, depending on the console switch
setting.
DATANET-30 GENERAL ASSEMBLY PROGRAM
DATANET-30 General Assembly Program has operating procedures identical to those for the
GE-225 General Assembly Program.
The DATANET-30 General Assembly Program operates either from cards or a systems tape.
When the General Assembly Program is loaded from cards, it is referred to as a Card General
Assembly Program. When the assembly program is loaded from the systems tape, it is referred
to as a Tape General Assembly Program.
Since cards or tape may be used as the input/ output medium, there is a separate set of operating
instructions for card assembly programs and tape assembly programs.
The General Assembly Program is made up of three separate programs: pass O, pass 1, and
pass 2.
The input to pass 0 is the symbolic program. The output from pass
O
plus the output
from pass 1 is the input to pass 2. The output from pass 2 is the assembled program.
Cards or tape ·may be used as the input and output for all passes. Whether cards or tape are
used determines the setting of console switch 4.
A
flow diagram of the three assembly pro-
grams is shown in Figure A-1.
The minimum hardware requirements for the operation of the DATANET-30 General Assembly
Program are:
1.
Card reader
2.
Card punch or magnetic tape
3.
Typewriter
4.
8192 words of memory.
Options and Console Switches
The console switches (A-register input switches} of the GE-225 are used to indicate the periph-
eral configuration available while using the General Assembly Program. All switches, with
the exception of switch 19, should be set initially and remain the same through all passes of
the assembly program.
