Thanks for the feedback. To be fair, the PROC approach is also "easy to understand" if the implementation is hidden in a library (which it is: I copied PROC_setptr from dlglib.bbc). That would be an e

One of the few things that irritates me about BBC BASIC is that there is no built-in way of assigning a memory address to a structure, something that you commonly want to do if (for example) you are u

I was trying to track down the cause of excessive CPU usage in one of my programs and eventually traced it to this code: REPEAT OFF K% = INKEY(4) UNTIL K% <> -1 At first glance this looks entirely inn

I have created a poll over at the forum to ascertain the degree of interest in having a breakpoint capability in SDLIDE (one of the two IDEs supplied with BBCSDL). If such a capability were added it w

I've updated bbcide.exe to v0.19 (I discovered today that some of the debugging features, for example breakpoints, were broken by the changes in BB4W v6.13a). It can be found in the files area of this

I have updated the Console Mode editions of BBC BASIC to version 0.25. The main changes in this version are: Fixed a bug which caused the expected 'Type mismatch' error not to be reported on assigning

I've released version 1.14a of BBC BASIC for SDL 2.0 - the cross-platform programming language for Windows, MacOS, Linux, Raspbian, Android and iOS. The changes in this version are as follows: BASIC I

I don't know what's going on over at the forum. It looks like the admin has set everybody (or at least a subset of members) to moderated status but isn't approving any posts, which is odd. I recently

When 'compiled', the relevant flag bit is controlled by the REM!NoPrinter compiler directive, not the registry. If your program does not contain that directive, the default printer will be enabled.

Of course not - it's the absence of UsePrinter that is triggering the bug! To fix it you must create that value, either manually, by running the BBC BASIC program, or by downloading and running the .r

For anybody who is uneasy about doing that manually (and it really isn't that scary, compared with the damage that a rogue BBC BASIC program could wreak!) there are two other ways of making the necess

This thread is about the printer failure reported by the OP, which turns out to be because of a bug in the BB4W IDE (which is entirely my responsibility and nothing to do with Windows). Please keep it

Whilst this may be true, it is usually a safer bet to blame the application program, and that turns out to have been the case here. Windows, whatever its faults, is used by millions of people so if a

As reported in another thread, a bug in the BBC BASIC for Windows IDE has been discovered. There is an uninitialised flags bit which means that there is a 50:50 chance that the default printer will no

The OP reported that a 'compiled' program worked as expected (I assume on the same PC) which suggests that Windows was not responsible, on this occasion. Another respondent reports that explicitly sel

Is anybody familiar with JSON files? If you are, can you please pop over to the forum here and try to help the OP.

No: I said "it shouldn't have changed spontaneously" in my reply, but I still think it's worth checking to be sure. You can't 'accidentally' modify the registry so I think your reluctance even to look

Have you checked your UsePrinter setting, as documented here? It shouldn't have changed spontaneously, of course, but since the specific purpose of that registry setting is to prevent the default prin

I have updated the Console Mode editions of BBC BASIC to version 0.24. The changes in this version are: 'Fatal' errors (e.g. 'No room' and 'Bad program'') now return to the immediate mode prompt rathe

Updated again to version 0.23. I have further optimised this version so that there are now two timeouts: a shorter timeout for distinguishing between the Escape key and an 'escape sequence', and a lon
