Correct, you can also opt for the usage of an OFFSET variable:

Code:

math OFFSET = 16
get SIZE asize
math SIZE - OFFSET
get NAME basename
string NAME   .ren
log NAME OFFSET SIZE

Just add the following to the previous script:

Code:

set MEMORY_FILE binary "\x05\xB9\x69\xBC\x1E"
append -1
log NAME 0 5 MEMORY_FILE
append

In the current beta of quickbms the append mode even works with the put* commands, but they are mainly meant for working memory files so this is just a FYI note
