I have a file "file.fle". It's size 40 bytes. I need add 5 bytes (01 fe 48 9a 53) to its end and keep 40 original bytes at the beginning. New size of "file.fle" should be 45 bytes. I tried to use MEMORY_FILE, PutVarChr, append commands but i'm stuck. How to write right bms script for that?

A solution can be the following:

Code:

set NAME string "new_file.fle"
set MEMORY_FILE binary "\x01\xfe\x48\x9a\x53"
get SIZE asize
log NAME 0 SIZE
append
log NAME 0 5 MEMORY_FILE

Thank you very much for quick response! I just replaced first string in you code on (i'm using one script to add same data for different files):

Code:

Get NAME filename

and it works perfect.

Yeah good.
Usually I prefer to create a new file, for example with some instructions like the following:

Code:

get NAME basename
get EXT extension
string NAME   "_new."
string NAME   EXT

It may be a good suggestion for the future.
