$ create/nolog 'f'
XModified once more to compile with Microsoft C V3.00, and VAX/VMS.
XThe CI86 code is still there, surrounded with #ifdef CI86...#endif
X 
XUsage is:
X`009uuencode `091input `091output`093 `093
X`009`009if output not specified, write to stdout
X`009`009if input not specified, get input from stdin
X`009uudecode `091input`093
X`009`009if input not specified, get input from stdin
X 
XWARNING: Current restriction on VAX/VMS:  ASCII text files get
Xall CR/LF combinations converted to LF only during UUENCODE.
XThis should not be a major problem, as ASCII text files should
Xnot need to be "encoded".
X 
XAlso note that the return status is not consistent with VAX/VMS
Xusage, although the error messages should be OK.

X============================================================================
V==
XThe files described in the following paragraphs have been modified
Xfor and compiled under Computer Innovations C86.  Note that when
Xuuencoding a binary file, you must not feed the file to uuencode
Xthrough stdin--for some reason, this causes the file to only be
Xpartially encoded (I suspect that this happens when uuencode runs
Xinto a `094Z in the input--I have played around with putting stdin into
X'raw' mode, which failed to successfully correct the problem).  So
Xwhen uuencoding binary files, use the full two-argument form.  Note
Xthat uudecode is unaffected.

X============================================================================
V==
X 
Xuudecode and uuencode are easily implemented under MSDOS as well.  Here
Xare the sources for Microsoft C v3.0, but if you have another kind of C
Xcompiler, there should be perhaps only 1 change -- the output file of
Xuudecode and the input file of uuencode must be in binary format.
X(ie.  binary files, like .EXE files may have byte patterns that are the
Xsame as `094Z, which signals end-of-file in non-binary (text) mode).
X 
XIf you need more info, write back.  Note that the included files are
X*not* in "shar" format -- you will have to use an editor to cut the
Xfiles out.
