Arrays are passed by reference. If you pass an array as an argument to a procedure and modify that argument within the procedure, the array will have the modified values upon return from the procedure call. For example:
proc fred( string $myArray[] ) {
for ( $i=0; $i<size($myArray); ++$i ) {
$myArray[$i] = "fred";
}
$myArray[$i] = "flintstone"; // add to the end of the array.
}
string $a[] =`ls -geometry`;
print("Before call to fred\n");
print $a;
fred($a);
print("After call to fred\n");
print $a;
produces this output:
Before call to fred
nurbConeShape1
nurbConeShape2
nurbSphereShape1
nurbSphereShape2
After call to fred
fred
fred
fred
fred
flintstone
