Software Product Description
PRODUCT NAME:

lAS, Version 2.0, Interactive Application System

DESCRIPTION:
lAS is a general purpose operating system that runs
on the PDP-11/45, PDP-11/50, PDP-11/55, PDP11/60, or PDP-11 /70 central processors. lAS supports
three concurrent modes of processing: real-time, interactive, and batch. The system includes the PDP-11
MACRO assembler and optionally supports several
language processors and data management systems.
lAS provides:
• multiple concurrent processing modes to optimize
system resource usage
• general interactive multi-language services for up to
32 simultaneous users
• an easy-to-use interactive and batch program development interface that operates concurrently with
real-time processing
• operating system services that automatically share
processor and memory resources among interactive application programs through time slicing and
swapping
• program and data protection in system and user
interactions
• interactive interface for the system operator to allocate system resources
lAS consists of elements of the RSX-11 D operating
system executive that provide real-time processing,
and a timesharing executive that controls the interactive and batch processing facilities. Real-time,
interactive, and batch processing can take place concurrently and service is normally delivered in that order of priority.
Memory is partitioned into areas controlled by the real-time executive and an area controlled by the timesharing executive. Tasks in real-time partitions are
scheduled by priority, as in RSX-11 D. The timesharing partition is used for interactive, batch, and noncritical real-time tasks.
The timesharing executive schedules interactive tasks
using a dynamically computed time slicing algorithm.
If necessary, the executive also swaps tasks in and
out of memory from one or more swapping areas on
disk.

SPD 14.65.4

The timesharing executive schedules and swaps
batch tasks in the same manner as interactive tasks.
Batch tasks normally receive the CPU time available
after real-time and interactive tasks are serviced. It is
possible, however, to guarantee a minimum amount
of CPU time to batch processing.
lAS is oriented toward the interactive terminal user.
Terminals are normally associated with a program
called a Command Language Interpreter (CLI) that
conducts the dialogue with the user and calls system
services to carry out the user's requests. Two CLls
are included with the lAS system: the Program Development System (PDS) and the System Control Interface (SCI).
All real-time, interactive and batch facilities are available to the PDS user. The system manager can define
privileges and assign passwords uniquely for each
PDS user to control the facilities an individual is allowed to invoke. PDS:
• prompts user for command arguments and supplies default values
• provides access to multiple 13nguage processors,
file system, utilities, and system status information
• accepts indirect command files for automatic command input
• enables user to submit batch command files
• conditionally executes commands in either indirect
command files or batch streams based on error
tests
• provides access to real-time program control commands
SCI is the system operator's terminal interface. It enables the operator to control system resource allocation dynamically, including the assignment of terminals to particular CLI's. For example, the system
operator can declare programs other than PDS as the
CLI associated with a terminal, e.g., the BASIC language interpreter. A user at that terminal can then
invoke only that program and no other. SCI:
• can be invoked from any deSignated user terminal

• can be used to control allocation of resources to
users and CLI assignment to terminals
• can be used to monitor system status and tune the
system dynam ically
PDS, SCI, and most other system programs provided
with lAS are shareable and reentrant. Utility programs
include:
• a complete set of file control utilities, such as file
dump, file verification, volume preservation, disk
save and compression, file comparison
• two editors: an interactive character-oriented editor
and a line-oriented batch editor
• program development utilties such as the MACRO
assembler, the Task Builder linker with automatic
overlay support, and the on-line debugger which is
linkable to individual tasks
• system generation program
• program library management program
• PLOT55 graphics subroutine for using graphics features of the VT55 terminal
• Linker (Task Builder) with automatic overlay support
Users writing their own CLis or other application programs can call the Timesharing Control Services
(TCS) for controlling and executing tasks and sub
task. User-written interactive programs:
• can be multi-tasked and engage in event flag communication
• can be shareable, reentrant, and share common
data areas
• can execute concurrently with other application
tasks, be time slice scheduled and swapped
User-written Command Language Interpreters can also:
.
• run other tasks to multiple levels
• engage
in
inter-task
communication
send/receive directives or "command lines"

using

Programs in all three processing modes have access
to the lAS file system, which is compatible with the
RSX-11 family of operating systems. Protection is separately controlled for four categories of user (system, owner, group, world) for four types of access
(read, write, extend, delete). Magnetic tape labels are
checked and ANSI standard magtape format is supported.
Other facilities are:
• spooling of output to printers and non-interactive
terminals
• spooled batch input from record-oriented devices
and from files submitted by users

•

•
•
•

accounting information recorded for interactive and
batch users showing CPU and memory usage and
connect time
automatic logging (on disk) of peripheral device errors and memory parity errors
optional user mode diagnostic device exercisers for
on-line checkout of peripherals
block mode terminal support
