I suspect that procmail is trying to substitute its own value for $#
(number of command line arguments) before it even gets as far as
calling the shell to do the echo. ${#NUMBER} as a way of returning
the number of characters in $NUMBER is a more recent shell invention
than procmail's 20+ years old parser is prepared to deal with.
You might be able to work around that by doing this:
LENGTH=`echo ${#NUMBER} ; :`
The semicolon will tell procmail that it can't execute the command
directly and must instead spawn a shell, which may bypass its attempt
to do the variable substitution internally.
If that doesn't work, you'll have to do something like
:0
* 1^1 NUMBER ?? .
{ LENGTH=$= }
(I fixed the HT -> TH in both examples above, in case you didn't notice.)
