With youre shorting it works now as I wanted it to do.

      for ( $sysDescr ) {

         s/$prefixSysDescr|$prefixSnmpWalk/$hostName$TAB/ && do {
            $OutputLine = $_;
            last;
         }; # substitute some prefixes

         $OutputLine = $OutputLine . $SPACE . $_;

      } # process output

If I run the script with 3 hostnames, it produces now the following output (the IBM machine produces normally an output over a couple of lines):

$ perl -w getSysDescr.pl
82 >>omServer1  Sun SNMP Agent, Ultra-80

Pause in (main). Go [y|Y]; Quit [q|Q]: y
82 >> omServer2  IBM PowerPC CHRP Computer Machine Type: 0x0800004c Pr
+ocessor id: 00C9FC8A4C00 Base Operating System Runtime AIX version: 0
+5.03.0000.0060 TCP/IP Client Support version: 05.03.0000.0063

Pause in (main). Go[y|Y]; Quit [q|Q]: y
82 >>omServer3  No response arrived before timeout.

Pause in (main). Go [y|Y]; Quit [q|Q]:q

Nevertheless I'm still interested why now the use of the variable $prefixSnmpWalk works.

Beside:never mind my avoiding the if-clause. In this case I try to avoid an if-then-elseif-elseif .... I prefer select-case-else-endselect and substitute it with the for-loop
