Array Process

Perform an operation on the elements of an array as a group.

Rotate shifts all the elements to left or right, and puts the end one back at the other side.

Squash removes array indices for which no value is assigned e.g. if %var1=one and %var3=three, squash will result in %var1=one and %var2=three.

The numeric sorts use the first number they find in each entry e.g. a3c, b5, 1x becomes 1x, a3c, b5.
