Use a WHILE loop to form an Test-than-Loop construct Used most often for loops with a non-numeric-range test while ( $line = <STDIN> ) { print "ECHO: $line"; } Want an infinite loop? while ( 1 ) { print "Infinite loop!\n"; }
while ( $line = <STDIN> ) { print "ECHO: $line"; }
while ( 1 ) { print "Infinite loop!\n"; }
