Sorry, i write comments to quicly
But, I suggest another approach :

;reads the 10th to end of file (1-based offsets, 9th to end in 0-based).
exten => s,1,Set(foo=${FILE(/tmp/test.txt,10)})
 
;reads the 10th to 29th character in the file (9 to 28 0-based).
exten => s,1,Set(foo=${FILE(/tmp/test.txt,10,20)})

; Replace 10 chars beginning at the 19th of the file with "bar" (1-based
offsets)
Set(FILE(/tmp/foo.txt,19,10)=bar)

; Replace all chars from the 19th to last with "bar"
(1-based offsets)
Set(FILE(/tmp/foo.txt,19,-1)=bar)


I stand by my suggestion that appending to the file use the L0 line
specification, or if you think it's more clear, L-0 (take back 0 lines
from
the end). 

I prefer to keep L-1 for add a line :
exten => s,1,Set(${FILE(/tmp/test.txt,L-1)}=bar)

And to add a string :
exten => s,1,Set(${FILE(/tmp/test.txt,-1)}=bar)


I reserved the '0' for 'begin of file' :
; truncate the file and write 'bar'
Set(FILE(/tmp/foo.txt)=bar)

; equivalent to
Set(FILE(/tmp/foo.txt,L0)=bar)
