Subject: File converters
I have uploaded a number of files to watsun in my home dir under
jan25. The suffixes are:
.c C language source code
.pm VOS executable in stream format
.cm VOS command macro
.vos My hexified format
.boo BOO format
The files are:
ckbunb The un-BOOer from the C-Kermit distribution
ckbmkb The BOO-er that goes with it
cklcvt converter from pm stream to pm fixed
ckltxt Hexifier for the format I made up
cklxtr Un-hexifier that goes with it
The format I came up with is almost only hex-ifying, except that if
the line is all 0000...000, count it. as you count up and get to
something that isn't nulls, output that as Znn where nn is the hex
number of null lines. Also, don't split an output record boundary
within a Z record. A line is 32 bytes, or 64 hex digits. It works,
but it takes several minutes to use the command macro un-hexifier on
the cklxtr.vos file, but the cklxtr.pm will run it in just a second or
two. These really aren't "distributable quality" yet, but they do give
us a basis for looking at file formats and converters. The hex format
only processes program modules correctly, not any of the other file
types.
