Very strange. A friend of us picked the same document from the gambas list, and put it on the italian site of gambas (www.gambas-it.org). Anyway, I attach a tarred copy of the new document, which contains corrections.Benoît Minisini ha scritto:No: there is no HTML at all in your mail.
My copy of the documentation is different. With all evidence, a correction about this topic was added after I downloaded the gambas sources from sourceforge. Anyway, the important thing is that now the documentation is correct.It is explicitely said that "WRITE #Pointer" is not supported anymore in Gambas 3, in the WRITE documentation page. And so on for the READ instruction.Sorry, I think that it is not so clear. "No more supported", or equivalent semantics, is totally absent from the page. It is true that there is a frame specifying the syntax for READ in Gambas3, but it speaks only about "READ #Stream". This makes me think that the "READ #Stream" syntax or behavior changed, not necessarily that pointers are no more valid. Perhaps would be better to say something more in the first frame, the one just below the title of the page: "WARNING! The syntax has changed in Gambas 3. READ/WRITE with pointers is no more supported in Gambas 3. See below."That is explicitetly mentioned in the READ & WRITE documentation page. See the joined screenshot if you don't trust me. :-)
Note that 'WRITE #p, 0, 1' does not write one byte, but only the integer 0 on four bytes. You must do 'WRITE #p, chr$(0), 1'WRITE #p, outq writes four bytes as outq is an integer, not one byte.And so on... I think you must check all your use of the WRITE instruction, which write a number of bytes that depends on the datatype of its second argument.
I corrected the above errors, and attach the revised project.It worked anyway, because the extraneous bytes written after the intended ones, were afterwards rewritten with correct values. Perhaps the compiler could reject statements like "write #p, 0, 1", or perhaps gambas2 is going to museum in favor of gambas3.
In a previous email I said that by declaring a constant as a byte, and then writing it out with a "write #pointer...", 4 bytes were written instead of one. This is not totally true - I did'nt verified. What is true, instead, is that declaring a constant as byte, and then writing it out to a stream, 4 bytes are written. This was verified in an old temptative of the drum machine, where OSS was used instead of alsa, and a gambas stream (file) was used to write to the file /dev/sequencer2.
