Re: Proposal about the file system

The redundancy that file header space is duplicated in the first 64 bytes of the raw representation of the file and the file header in the directory file is specific to the QL5A/B and similar file systems. Systems that use a different disk file system might not necessarily have that duplication (ATR...

Re: Issues and questions.

Peter, My experience with the SCART-HDMI scalers (the "boxy" type that was once linked here) in the meantime is the following: They seem to be all the same - No difference between time manufactured. I have three of them now purchased over about five years and they all behave the same with ...

Re: Issues and questions.

The (definitely questionable) make of the "case" would be my least concern with this box. The price tag on the OSSC is my main one, to be honest. I'm a bit unwilling to spend that amount of money to have the benefit of a QL spitting out an acceptable picture when I can have a new Q68 with ...

Re: Proposal about the file system

Giorgio, I don't see any dangers using a field for the purpose intended by the OS designers, at least if the programs are used and programmed in a proper way. (BTW, DEC VMS does it in exactly in the same way, so the concept can't be all that wrong...) I try to explain it with a simple example: I am ...

Re: Proposal about the file system

Giorgio, the file backup date is not used by the system. Various backup programs do, however, use it for the intended purpose (compare modification date with backup date and decide a file does not need to be part of an incremental backup in case the former is earlier than the latter). Any change in ...

Re: Test if a directory exists

Dilwyn, working with FMAKE_DIR or MAKE_DIR is a bit of a dangerous path. It will work in theory, but you will run into hard to fix issues in case the driver has to move files into that newly made directory: win1_LETTER_TXT exists, win1_LETTER_DOC exists you try to find out whether the directory win1...

Re: Test if a directory exists

The behavior you see has to do with the fact that opening a directory on a valid and working device may not fail on QDOS for reasons other than the file exists and is no directory (That has to do with the fact that directories were a late addition to the OS and also somewhat with the way the default...

Re: Hello from Greater Toronto Area, Ontario, Canada!

I do notice from your screenshot that you are using one of the finest QL Toolkits around, DJToolkit. I wrote that one! So what does DJ stand for? I had up to now assumed it was Dilwyn's initials :-D Because Dilwyn used to sell this in the past (probably because no one wants to deal with a Scotsman ...

Re: QL Tinkering

Interesting idea, Per!

Very unfortunately, however, this will not compile using Turbo - This doesn't allow expressions in DATA statements.
A shame there isn't anything like a LABEL statement in S*BASIC.

Re: QL wont work

Hi It is a standard one fixed to the heatsink but would this of caused any more damage elsewhere if it's putting out too much volts. If you really had 7.5 Volts on the 5V rail, this has probably caused a lot more damage in all places - Some of the more robust chips might survive this for a few minu...
