GZIP support

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

That's internal to the ZIP library; I'll pass it on to the developers.

Ditto.

I doubt it, but it's not my code. It seems like a bug; I'll pass it on to the developers.

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.

The help is wrong; valid levels are 1 - 6.

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

NITV. I don't know why this would be useful, but you can submit a suggestion for the next major version.
