Unfortunately it isn't because it's not just a basic extension. The functionality itself is implemented in globally visible "things" so that it can be used from any language, the basic commands are just wrappers for them. So what would probably happen is that the linked copy would overwrite any existing "things" with the same names and everything will crash once you remove the job again because of dangling pointers. > Whatever, I will update the program for the latest version and hope > for the best.

30 if (a<>0 AND b/a=5) The first condition (a<>0) is NOT met and so, in any other programming language I use, the second condition isn't even tested, as the result will be "false" anyway because of this. Standard BASIC approach is to evaluate first expression, store the result somewhere (stack?), evaluate the second expression and store the result. And then evaluate the AND operand (with parameters already stored - on stack?) as the last. (Tiny Basic, ZX Spectrum Basic) Maybe SBasic does the same or similar. ___ QL-Users Mailing List

Re: [Ql-Users] Qbase
Hi, I believe that the Api has remained pretty stable since v. 7. Wolfgang Yes, but if the API has changed from version to version, then it WILL fail for some users who are using a different version to the one that I am writing for in my program. Therefore linking it seems like a good idea. Whatever, I will update the program for the latest version and hope for the best.

Your best bet is probably to adapt your program to the latest version. Wolfgang A question about QBase and QMenu. The menu extensions are used fairly extensively in QBase. However, the program was originally written in 1998 with whatever version of QMenu was current then, and it doesn't seem to work properly with the later version (version 7.66) which is distributed with QPC. I also have a version 5.06, which appears to work much better with QBase, and I thought it might be a good idea to link it into QBase with Q-Liberator and avoid problems for people using later versions. The other possibility is to update the QBase code, but for this I would need a manual, which seems to be unavailable (is it really still commercial?). I did purchase a copy of QMenu in the 1990s, but I can't find the manual, which I assume is buried somewhere in my attic. So, does anyone know the correct parameters for linking menu_rext into a Q_Liberator compiled program? Thanks, D.

Re: [Ql-Users] Qbase
Hi, the problem is that these parameters are likely to vary from version to version, as they are offsets into the file... Your best bet is probably to adapt your program to the latest version. Wolfgang A question about QBase and QMenu. The menu extensions are used fairly extensively in QBase. However, the program was originally written in 1998 with whatever version of QMenu was current then, and it doesn't seem to work properly with the later version (version 7.66) which is distributed with QPC. I also have a version 5.06, which appears to work much better with QBase, and I thought it might be a good idea to link it into QBase with Q-Liberator and avoid problems for people using later versions. The other possibility is to update the QBase code, but for this I would need a manual, which seems to be unavailable (is it really still commercial?). I did purchase a copy of QMenu in the 1990s, but I can't find the manual, which I assume is buried somewhere in my attic. So, does anyone know the correct parameters for linking menu_rext into a Q_Liberator compiled program? Thanks, D.

The test _dbs has 3111 records by 6 fields making 18666 menu items. That is well within the limit of items (<32K) WMAN2 can handle in the AW. Records times Fields must be less. But there is also a limit in S*Basic of 65K for indexing second and third dimensions, in this case Fields x Field_length (including length word). As you used Fields as the first dimension instead, 2nd (Records: 3111) times 3rd (length: 20 +2) would be just too much. As records will in most cases be the highest number, making it the first dimension is the best choice. So checking these limits and using paging is the only option for a large database that exceed these limits.
