If you really want to do it using substr and index then here is one iterative method:
use strict;
use warnings;
my $line='PSAPPSRV.26476584 (6) 01/02/19 06:30:30 GetCertificate(3) Re
+turning context. ID=PTWEBSERVER, Lang=ENG';
my $SpaceChar = ' ';
my $result = $line;
for (1..4) {
$result = substr ($result, index ($result, $SpaceChar) + 1);
print "$result\n";
}
Here's a simpler one with split instead:
#!/usr/bin/env perl
use strict;
use warnings;
my $line='PSAPPSRV.26476584 (6) 01/02/19 06:30:30 GetCertificate(3) Re
+turning context. ID=PTWEBSERVER, Lang=ENG';
my $SpaceChar = ' ';
my $result = (split ($SpaceChar, $line, 5))[4];
print "$result\n";
Update: edit of first snippet to remove expensive no-op.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
