+# With two arrays on the stack, cat pops
+# them, concatenates them, and pushes the result back
+# on the stack. This works with arrays of integers,
+# strings, or whatever. For example,
+
+[1 2 3] [4 5 6] cat # result: [1 2 3 4 5 6]
+[`abc' `def'] [`ghi' `jkl'] cat # result: [`abc' `def' `ghi' `jkl']
+
+# To concatenate more than two arrays, push the number of arrays
+# to concatenate onto the stack and use ncat. For example,
+
+[1 true `a'] [2 false `b'] [`3rd array'] 3 ncat
+# leaves [1 true `a' 2 false `b' `3rd array'] on the stack
