You are right. The time dropped from 1.05 seconds
to 0.9

Amazing! This make the time drop from 0.9
to 0.7 seconds.

This is the handler:

local v1

on mouseUp
  
  put the ticks into zxcv
  
  -- this line put the ticks into a variable to count
the time
  -- that takes to execute this handler. There are 60
ticks in a second
  
  put the imagedata of img 1 into asd
  delete char 1 of asd
  -- the first char of the imagedata is the alphadata
or maskdata
  
  repeat with i = 1 to length(asd) step 4
    get binaryDecode("H*", char i to i+2 of asd, v1)
    put v1 after fldhex
  end repeat
  
  put length(fldhex) into lenghtofldhex
  repeat with i = 1 to lenghtofldhex step 60 -- I want
60 chars per line
    put return & char i to (i+59) of fldhex after
fldhexa2
  end repeat
  
  put empty into fldhex
  put toUpper(fldhexa2) into fld "hex"
  put ((the ticks - zxcv) / 60) && "seconds to create
the hexadecimal data from binary imagedata"
end mouseUp

But still, i feel curious to know WHY binaryencode()
could put his results after a variable and
binarydecode
reports an error. The sintax of both functions is
similar so, Where did originates this error?

put binaryDecode("H*", char i to i+2 of asd)after var
-- produces an error!
put binaryEncode("H*", char i to i+2 of asd)after var
-- works perfectly!

Thanks again Dar, for your extraordinary help 
with this task.
