# 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
