Viewing and changing parameter settings
Opening a semipublic file
The following example illustrates the opening of a semipublic file.
The user attempts to open CENSUS, which is a semipublic file:
?OPENC CENSUS
*** M204.0347: PASSWORD ?########
The user presses a carriage return. The file is opened, and the user is granted
default privileges that do not allow the user to update the file. The following
message is displayed:
*** M204.0620: FILE CENSUS OPENED -- NO UPDATES ALLOWED
Viewing and changing parameter settings
Before a user runs a file retrieval that results in a printed report, the user might
want to check the values of the parameters that control the spacing of printed
output. Parameters are variables that define terminal characteristics, the length
of user input and output lines, file characteristics, table sizes, and other
information at particular installations. The basic types of parameters are:
•System
•File
•User
Some parameters can be set or reset only by the system manager or by a file
manager. Others can be reset by the user. All the parameters have default
values provided by Model 204. The parameters that affect terminal operations
are summarized in the Model 204 Parameter and Command Reference
Manual.
Using the VIEW command
The user can display the current values of all the parameters or a subset of
parameters by means of the VIEW command, which can be abbreviated to V.
The format of the VIEW command is as follows:
VIEW parameter [,parameter]
•••
Special sets of parameters also can be displayed. For example:
This command... Displays all...
VIEW ALL Parameters
VIEW SYSTEM System parameters
VIEW USER User parameters
