Consider this (notably, the difference between $localPrivateVarX and $localPersistentY):
#!/usr/bin/perl use strict; my $GlobalA = 1; foreach my $notAGlobalB (qw /X Y Z/) { &displayDashedLine(); my $returnValueFromM = &subM($notAGlobalB); print "Return: \$GlobalA = '$GlobalA', \$notAGlobalB = '$notAGlob +alB', \$returnValueFromM = '$returnValueFromM'\n"; my $returnValueFromN = &subN($notAGlobalB); print "Return: \$GlobalA = '$GlobalA', \$notAGlobalB = '$notAGlob +alB', \$returnValueFromN = '$returnValueFromN'\n"; } &displayDashedLine(); exit; sub displayDashedLine { print "----------------------------------------\n"; } sub subM { my ($parameterM1, @everythingElse) = @_; my $localPrivateVarX; if (!defined $localPrivateVarX) { $localPrivateVarX = 0; } $localPrivateVarX++; print " SubM: \$GlobalA = '$GlobalA', \$parameterM1 = '$paramete +rM1', \$localPrivateVarX = '$localPrivateVarX'\n"; return; } { my $localPersistentY; sub subN { my ($parameterN1, @everythingElse) = @_; if (!defined $localPersistentY) { $localPersistentY = 0; } $localPersistentY++; print " SubN: \$GlobalA = '$GlobalA', \$parameterN1 = '$para +meterN1', \$localPersistentY = '$localPersistentY'\n"; return; } } exit; __END__
