Here are a few sources of information about Glish:

and Systems Conference

ABSTRACT: This paper describes the Glish programming
language. Glish is a dynamically typed, array oriented language
which also supports distributed clients. Glish has integral,
floating point, string, complex, and heterogeneous record values.
Any of these values may be used as part of the interpreter to
client communications. Both synchronous and asynchronous client
interaction are supported. The
AIPS++ project
at the NRAO
is using Glish as the basic command line interface and as the backbone
for internal control and communication. Glish may also be used for
communication between AIPS++ and telescope control systems; this is
the case with the Green Bank
Telescope.
- Glish: A User-Level Software Bus for
Loosely-Coupled Distributed Systems from the Proceedings of
the 1993 Winter USENIX Technical Conference
-
ABSTRACT: We describe Glish, an interpreted language for
building distributed systems from modular, event-oriented programs.
These programs are written in conventional languages such as C,
C++, or FORTRAN. Glish scripts can create local and remote
processes and control their communication. Glish also provides a
full, array-oriented programming language for manipulating binary
data sent between the processes. In general, Glish uses a centralized
communication model where interprocess communication passes through the
Glish interpreter, allowing dynamic modification and rerouting of
data values, but Glish also supports point-to-point links between
processes when necessary for high performance. Glish is available
via anonymous ftp.
- Glish: A Software Bus for High-Level
Control from the Proceedings of the 1993 International Conference
on Accelerator and Large Experimental Physics Control Systems
-
ABSTRACT: Glish is a software system for building high-level
control applications out of modular, event-oriented programs. Glish
provides these applications with a high degree of flexibility, so they
can adapt quickly to changing requirements. We describe the strengths
of the "software bus" approach, how Glish can direct and modify
interprocess communications within a distributed application, and how
the system is currently used for orbit-correction at the
Advanced Light Source at LBL.
The following papers are only of historical interest:
- A Language, Server, and C++ Class
Library for Event Sequencing from the Proceedings of the
1989 International Conference on Accelerator and Large Experimental
Physics Control Systems
-
ABSTRACT: Many accelerator control tasks are well specified
as a sequence of operations, each step of which is contingent upon
the status of other operations or sequences. To enable the rapid
creation and modification of such sequences we have devised the
Glish language. Sequences are described in Glish in
terms of asynchronous hardware and software events, where
an event is the notification that a particular thing has happened and
the value associated with that notification. Events are produced and
consumed by Unix processes. One uses Glish to write
expressions which specify how events associated with the process
depend on combinations of other events. We describe the Glish
server, which manages Glish events distributed across a
network, a C++ class library for Glish clients, and
operational experience gained in using Glish to control an
accelerator physics experiment at the Fermilab Tevatron.

Describes Glish's original transport layer, which has recently
been replaced with a C++ version.

Describes one of the original uses of Glish, a use which is very
similar to that of AIPS++.
