As I rarely get time to touch a QL nowadays, can anyone help with this query received:

I am sorry to trouble you again especially on a weekend.

I am trying - without success - to unzip a number of zip files and I thought that I had ACP installed on my QL (QPC2 actually) but not so !!!

Therefore I have downloaded unzip541xQ.zip from your site. having read just about everything that I can find on this topic, I have managed to unzip the .zip file inside the QL environment - I once got caught out using Winzip in the PC environment and learned about missing headers etc.

What I really want to do is get ACP running again but every time I try EX or EW ing ACP.obj (or_obj) I get an 'invalid parameter' fault. I guess that my copy of ACP_obj must be corrupt.

Back to unzip541xQ_bin, - I cannot find where to tell it the name and location of the zip file that I want to unzip!! like Win1_acp4e01_zip. What have I missed in the README documents?etc.

The other thing I have not done in OH SO MANY YEARS is used the config files - I have replaced them with NEW in case my old ones are corrupt but cannot remember whether to exec them or lRESPR them.
I guess that I could try both and see what happens.

I might be wrong, but doesn't ACP require a "special" version of the QLiberator runtime to be installed?

Cheers,
Norm.

Hi Dilwyn,

According to Jonathan Hudson's web site, the file: unzip541xQ_bin

This file is a SFX file, so must be LRESPRed, this will generate a UNZIP541 executable.

So, download the file: unzip541xQ_bin, I usually copy this to a QDOS container, ususlly a QWA file.

Then do LRESPR unzip541xQ_bin

And following the on screen directions

The ACP executable sounds like it has lost its header.

ACP requires an up to QLIB runtime

Maybe a QDOS container could be created with the archiver tools without the need to resort to the above file.

The 'invalid parameter' is probably due to a missing sigext30_rext, which must have been LRESPR'd before.
ACP's Godefroy did fix the Qlib_run (mod) but that may only show when running errors occur.
EX devn_unzip_exe; 'devn_filename_zip *-dram2_' should unpack the file to RAM2_.
Once ACP is started links to to Zip, Unzip etc. can be configured from there.
