Here's the code surrounding the error point simplified to a test function, without the Easyptr stuff. This should clarify what is happening line by line so we can see which keyword exactly is causing the issue.

Q_ERR_ON temporarily converts a procedure like OPEN_IN into a function (internally) so ...

Here you go:
13820 DEFine PROCedure Scroll_Bar
13830 REMark must use #2
13840 IF line_ptr(0) = 0 AND line_ptr(lines%) >= fl THEN
13850 sbht% = 10*lines% : sby% = 0 : REMark all of file shown
13860 ELSE
13870 IF line_ptr(lines%) >= fl THEN
13880 sbht% = 10 : sby% = 10*lines%-10 : REMark end of file ...

Assuming we're talking of v2.09, the code between those lines is as follows, in case it gives any clues:

18240 Q_ERR_ON 'open_in' : OPEN_IN #3,called$
18250 fer = Q_ERR : Q_ERR_OFF 'open_in'
18260 IF fer < 0 THEN An_Error fer : RETurn fer : REMark oops
18270 :
18280 fl = FLEN(#3) : REMark file ...

I'm very pleased it's been a successful project - people clearly appreciate your work.

Out of interest, do we have a rough figure of how many QIMSIs and QIMSI-Golds have been made?

Time for a HEX$(12648430,24) you mean?

Seriously, though, although this project isn't quite my, err, cup of tea, I'll be following it with quiet interest.

I wasn't too sure from reading the QIMSI Gold manual if the 47ohm resistor and clamp diode are already on the board (so needing only the 330 ohm resistor on the jack socket contact?).

What held me back from adding the network was the worry over a third cable tugging on the fairly fragile connection ...

When I eventually found the right screwdriver (long story, my son had put them back somewhere other than where I normally keep them), I opened the case and the network connector lead had come off the Q68 circuit board. I'd tried Martin's suggestion of shaking it to try to hear if something was loose ...

Hi Dilwyn,
A couple of idea's

Have you been inside the Q68 lately? Is the cable from the network sockets plugged in to the main board (and the right way round).

Do you have my IP network driver running on the Q68? If so it needs to be configured to use different network names, otherwise it will ...

Thanks Derek, I have just tried the three combinations of two of the machines. As they were two station networks, I just left everything as NET 1 with FSERVE running.

QL/Gold Card + Q68 : same results - no communication, times out after usual period.

Q68 + Aurora/SGC : same results - no ...
