The first parameter to split is a regex, not a string (except for a space). | in a regex has a special meaning, so you need to backslash it for the literal pipe symbol:
my @pargs = split /\|/, $id;
($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,
