    text
    copied!<p>Two pieces of ASCII text (one L = long and one S = short) were read into @arrayOne and @arrayTwo, respectively, for comparison. The following subroutine &amp;analyse gets two array references from the smart.pl code, but throws an error when checked via perl -c smart.pl. Unfortunately I can't figure out why: </p> <pre><code>68 sub analyse { 69 my $arraysize ; my $arrLref ; my $arrSref ; my $item_L ; my $item_S ; my $value ; 70 71 $arrSref = shift ; $arrLref = shift ; 72 $item_S = shift @{ $arrSref } ; 73 $item_L = shift @{ $arrLref } ; 74 75 $arraysize = $#{ $arrSref } ; 76 while ( $arraysize &gt; 0 ) { 77 $value = ( $item_S cmp $item_L ) ; 78 given ( $value ) { 79 when ( -1 ) { 80 push ( @mergedArray , $item_S ) ; 81 $item_S = shift @{ $arrSref } 82 } 83 when ( 0 ) { 84 push ( @mergedArray , $item_L ) ; 85 $item_S = shift @{ $arrSref } ; 86 $item_L = shift @{ $arrLref } 87 } 88 when ( 1 ) { 89 push ( @mergedArray , $item_L ) ; 90 $item_L = shift @{ $arrLref } 91 } 92 default { &amp;die } 93 } 94 } 95 } </code></pre> <p>Compilation is aborted with the following statements: </p> <pre><code> $ perl -c smart.pl syntax error at smart.pl line 78, near ") {" syntax error at smart.pl line 83, near ") {" syntax error at smart.pl line 88, near ") {" Global symbol "$item_L" requires explicit package name at smart.pl line 89.

Global symbol "$arrLref" requires explicit package name at smart.pl line 90. syntax error at smart.pl line 91, near "}" smart.pl had compilation errors. </code></pre> <p>Maybe someone else has a clue? Thx in advance –DrP-</p>
