re: control-chars & garbage in cpmug & sigm doc files

Herb;
       There are at least two possibilities:
1. the file is a squeezed file.
       if so, the middle letter in its filename extension is probably
       'Q'; so blah.doc is blah.dqc.
       For these, use USQ.COM (I think its on one of the bds user group
       disks, included in both CPMUG and SIGM libraries). USQ creates
       an unsqueezed version of the file. If you just want to read it,
       and don't mind keeping the file squeezed, use TYPESQ.COM.
    (there is another squeezer, pack.com & unsqueezer, unpack.com,
    but (a) I don't know where they are, and (b) they aren't as popular
    as sq, usq, and typesq.)
2. the doc file was created with wordstar or some other editor using
       control-characters and high-bits; to get rid of high-bits,
       use the [z] option on pip; for file blah, try
               pip blah.new=blah[z]
       this filters off high-bits, but leaves control chars.
Of course, there are other possibilities, but these are the one's I've
experienced on cpmug disks.
