Re: [Ql-Users] QL Today Assembly Language Book.
Norman, At your age you want to watch it. You might show your MSB, and the nurse might think it's your LSB.

[Ql-Users] QL Today Assembly Language Book.
A bug was recently found in section 1.2.1 where I described the format of data in registers as having the most significant bit at the right end. Duh! That has been corrected. If you need a corrected copy, it's the June 2020 release at https://github.com/NormanDunbar/QLAssemblyLanguageBook/releases/latest although that URL always gets the very latest version. If anyone needs a printed version, "Tinyfpga" on QL Forum has sorted out a print on demand setup, with my blessing, where it is at a cost or around £10.00.

Re: [Ql-Users] Select on
Hi, Here is my un-subtle attempt, how about summing the ASCII codes for the character string to be selected and use SELect ON to select the option based on the sum total, for example: 10 a$="Goodbye" 15 asum=0 20 FOR a=1 TO LEN(a$): asum=asum+CODE(a) 40 SELect ON asum 50 = 255: REMark ASCII Code sum for "Hello" 51 PRINT "Hello World" 60 = 364: REMark ASCII sum for "Goodbye" 61 PRINT "Goodbye World" 70 END SELect On 19/06/2020 20:35, pjwitte via Ql-Users wrote: On 19/06/2020 20:02, Daniel Baum via Ql-Users wrote: What about doing something like this.

This is what I came up with: 100 FOR i% = 1 TO 6 110 case$ = 'case' & i% 120 c% = case$ INSTR "case1 case2 case3 case4 case5 case6" 130 : 140 SELect ON c% 150 = 1: PRINT 'case 1' 160 = 7: PRINT 'case 2' 170 = 13: PRINT 'case 3' 180 = 19: PRINT 'case 4' 190 = 25: PRINT 'case 5' 200 = 31: PRINT 'case 6' 210 = REMAINDER : PRINT 'ERROR' 220 END SELect 230 : 240 END FOR i% This is obviously just a demo to illustrate the idea. It seems reasonably fast. In my case I was able to keep all the terms to more or less the same size. If there is a chance of ambiguity, one could wrap the terms in delimiters: c% = '#' & case$ & '#' INSTR '#case1#test this2#or this#etc#..#' Per ___ QL-Users Mailing List ___ QL-Users Mailing List
