Could someone provide me with a code example on how to combine two

The below takes two strings of the form (addr len), allocates a chunk of 

memory for them, and concatenates them into that allocated memory,

returning 

addr len.

: $cat2  ( $1 $2 -- $3 )

  2 pick over +  dup >r alloc-mem >r

Thank you very much Tarl. This word should be added to OpenBIOS. 

Please make sure whether the already existing functions (ie. in

openbios/forth/lib/string.fs) work for you before adding new stuff.
