In case your python file becomes a bit more complicated, you
shouldn't use workarounds as using backspace to come to a
binary format, because you then need exact indents (could be
tabs).
Better use (without replacing anything in mrgCmds) Matthias'
answer to use binary write.
Or the usual variant of that
put mrgCmds into url("binfile:" & fldr & "/theCmds.py")
