Hi
Using TCC 12.01.44
1) If I do
gzip /E1 B20100301.PVF.Z ..\B20100301.PVF
it takes a long time to generate a ZIP using LZW algorithm (many minutes). It is a few seconds if it is /E0
2) While it is doing this, it cannot be interrupted Ctrl-C or Ctrl-Break has no effect (until later)
3) If I then do
GZIP /V B20100301.PVF.Z
afterwards, I see
" The GZIP header is invalid."
is this correct?
4)
If I do
gzip /A B20100301.PVF.Z ..\B20100301.PVF
it works. If I do
gzip /A /L0 B20100301.PVF.Z ..\B20100301.PVF
I get back a Usage complaint, despite the fact that /L0 is valid according to the help file.
Usage : GZIP [A:[[-][+]rhsdaecjot] /A /E /Ln /M /O:[-]adegnrstu /Q /V] gzip arch
ive [@file] file...
5) From the help files, if I do GZIP /V (or UNGZIP /V), it is possible to see date time and filename (if available). Would it be possible to make compression method and level visible? Ditto for ZIP
Thanks
