decode multiple parts from one file

[Bernd Sokolowsky]

Hi,

I have a file that contains several encrypted messages.
All parts are encrypted for the same user ID. 

Is there an easy way to decrypt all these messages (to STDOUT)
without cutting the file into chunks first?

Furthermore, what's wrong here:

  594  gpg -e -a -r bsokolow@lucent.com -o textfile1.asc textfile1
  595  gpg -e -a -r bsokolow@lucent.com -o textfile2.asc textfile2
  596  cat textfile1.asc textfile2.asc >textfile1+2.asc
  597  gpg -d textfile1+2.asc
  598  gpg -d textfile1+2.asc >textfile1+2

You need a passphrase to unlock the secret key for
user: "Bernd Sokolowsky <bsokolow@lucent.com>"
1024-bit ELG-E key, ID 2A6A1B99, created 2000-09-29 (main key ID 907298C0)

gpg: encrypted with 1024-bit ELG-E key, ID 2A6A1B99, created 2000-09-29
      "Bernd Sokolowsky <bsokolow@lucent.com>"
gpg: uncompressing failed: unknown compress algorithm
