;	INDGEN Version 2(35)-3  generating IND Version 4(600)-3
;	This command file is used to generate your customised version of IND,
;	the advanced INDirect file utility inspired by RSX. You will be asked
;	a number of questions relevant to its operation. Some questions require
;	a numeric answer, some a yes/no answer, and some a text string. If you
;	press RETURN in response to a yes/no question, NO is assumed. For 
;	numeric questions of the form
; * Number of terminals ?[# R:10:20 D:15]
;	the two figures after R: indicate an acceptable range for your answer,
;	and the figure after the D: is the default (hit carriage return for
;	this.)  For text string questions, the figures after the R: indicate an
;	acceptable range for the number of characters in your answer.
;	You can save all your answers for later easy use by answering YES to 
;	question 3.
;	By default, INDGEN will type a long explanation of each question
;	before it asks you anything. If you are familiar with this procedure, 
;	you can suppress the explanation and just have the questions by 
;	answering YES to the first question.

;	By default, IND allows a user to exit a command file prematurely
;	by typing CTRL/Z in response to a question. Your command files can turn

;	The next question is about the POOL, an area of storage reserved for

;		due to overhead ;
;	(2)	The number of times the garbage collector runs to collect unused
;		space.
;	If your applications redefine string symbols frequently, it is worth 
;	increasing the size of the pool. Increasing it also increases the
