Re: Basic Shift Right

100 DEFine FuNction SHNR (num, times) 110   RETurn INT(num/(2*times)) 120 END DEFine SHNR No it should be INT(num/2^times). A shift right 3 times is division by 8, 4 times is division by 16 etc. This of course with all the limitations SB has on integers. Also it would be much slower than MC due to ...

Re: Basic Shift Right

Hi, I had realised the Shift Right or ROR in assembler is divding by 2, I was looking at too many trees, and not the wood... So the SHR FuNction reduces to: 100 DEFine FuNction SHR (num) 110 RETurn INT(num/2) 120 END DEFine SHR This assuming the number is not negative Actually in 68000 assembler th...

Re: SuperBASIC buffer BV.BFBAS

So is it reasonable to assume it's a 128 byte buffer? If another SuperBASIC command has changed it, it would not have made it smaller than 128 bytes? I know you could work out the length (start of the token table? minus the start of BASIC). The times I have seen the buffer used, the programs just u...

Re: SuperBASIC buffer BV.BFBAS

. If it's not big enough can you enlarge/reduce it? - Yes, although the respective QDOS ROM routine was never formally documented (S Goodwin discussed the topic of 'hidden' SB memory management routines in SQLWorld - vectored from a word-offset from the one routine we know - BV.CHRIX). I think thos...

Re: Defining Procedures & Functions

Pennell's QDOS Companion mentions that the BP.INIT vector allocates (PROCNUM+FUNCNUM)*8 bytes in both the Name Table and Name List. A NT entry is always 8 bytes, a NL entry is LEN(name)+1 bytes. As long as the average length of the names doesn't exceed 8 (including the length byte) you shouldn't wor...

Re: 8302 pinout help request...

Jan, You seem to have studied that code quite a lot - would it be possible for you to write a small expanation on the 8302 internal registers and their use? Interesting that the same serial hardware is used for MDV, this would open some interesting possibilities but as far as I know it's half duple...

Re: Testing for installed TURBO

That method should work with any toolkit function that ⋅ does not require any parameters ⋅ can be relied upon to return anything different from 0 or an empty string in the default case Toolkit II DATAD$ could be an example to test for Toolkit 2. Unfortunately, if TK2 is not pres...

Re: Issue 8 and WiFi

This is indeed leading into an interesting discussion - perhaps vanpeebles could split this into a new topic :D Given that the problematic software is generally going to be designed to be run on a basic 128K QL, then it should be possible to do this. In order to overcome some of the issues, I wonde...

Re: Winny problem

Tested. Is only the MAP that I can't understand why It can't be corrected. On the DIlwyn site there is the WINNY ROM dumped if you want to check it. I'm trying to ask to Tomas Kral to write a program that can check the sector 0 on the Winny and the on the QUBIDE and find the bad exadecimal imput. T...
