catremote
runs a separate utility program to submit the URL representing the query of a remote
catalogue and retrieve the results. The utility to be used is not hard-wired into catremote
, but rather is
specified using environment variable CATREM_URLREADER
(see Section 4). Several options are
available:
geturl
, a C program supplied with catremote
,
UrlReader
, a Java program also supplied with catremote
,
lynx

command-line browser,
wget
URL-retrieval tool.
geturl
is the default on Starlink systems. It is reasonably fast, as are lynx
and and wget
, though
UrlReader
seems somewhat slower. Brief details of using the various options follow.
geturl

so that UrlReader
is picked
up in addition to the standard Java classes. For example, I might set:
Note that it is necessary to specify the location of UrlReader
using CLASSPATH
rather than the
corresponding Java command-line option because the latter appears not to work on Compaq
Alpha/Tru64.

wget
is distributed as part of RedHat Linux systems and will probably only be available as part
of such systems. On these systems an on-line manual can be accessed by typing:
