Macro lcase$

[aw27]

Now, lower-casing Russian:

Original: КТО-ТО СКАЗАЛ — НЕ ПОМНЮ, КОГДА И ГДЕ
Small case: кто-то сказал — не помню, когда и где

It is true, they will reduce the font size!

;=====================
Jochen,
I think I understand what you mean.
Within my search routine - bevor and after Let esi=Lower$(edi) - esi is very frequently used with different offsets.
I am not going to change this. It works perfectly since years.

Three days ago I wanted to make the routine not case sensitiv changing the haystack and the needle to lower case letters and realized that lcase$(offset string) is not going to do the job on Ü Ä Ö.
Of course it would be nicer if it worked not case sensitiv.

You don't have to change it! I often use Let esi="..." because esi is a non-volatile register, and that produces short code. But a global variable Let some$="hello" works equally well, and there is no risk to trash the pointer.

Re case-sensitivity, Instr_("Sometest", "TEST", 1) works fine.

Jochen,
Tip of the day. My searchroutine used  "mov eax,find$(1,haystack,needle)".
It is not case insensitive and beside that returns -1 if the strings have the same length.
So - in this case  - you have to compare them.

mov pos,Instr_(1,haystack,needle,1) is definitely much better !
Many thanks Michael
MASM BASIC !!

Note the special modes, too:
mov pos, Instr_(1,haystack,needle, 1+4)  ; case-insensitive, full word
mov pos, Instr_(1,haystack,needle, 2)  ; case-insensitive for the first character (e.g. Hello = hello)

Yeah, Norwegian is the only valid codepage and programming language :t

As for the use of SetConsoleOutputCP() this is rather intrusive

And the next time you open a console, it's 850 again. So what?

First and foremost: SetConsoleOutputCP does not change the code page, when the console application terminates all is back to normal.

In relationship to your considerations and desiderata about who uses what and when, let's leave this behavioural part aside. However, I know the best approach is Unicode, the other approaches some times work some times do not work. Germans don't have a code page for themselves, but conversions upper-to-lowercase under CP 1252 appear to work well for Germans. Under OEM CP 850 may not work so well.

Actually, what I observe (Win7-64) is that the code page remains active within the same console instance. If you exit and restart the console, it's back to 850 (in my case), but if my application sets cp 65001, the next application launched in the same console will work with 65001, too. Which is pretty irrelevant in most cases - in a batch file, you either continue with 65001, or you set chcp manually.

@nidud

These old shells you like to use redraw themselves while the codepage has changed when probably should redraw after the application terminate and restored the codepage.
Actually, these are not the only problem these shells face. I prefer Explorer.exe as my shell although have purchased Take Command & TCC which is very good but a little buggy in my opinion.

I don't observe it neither in Windows 10 nor in Windows 7 64-bit when I build the above code:



However, I can observe it if I change the Font in the console System menu after the application terminates. I have no explanation for that, right now.  :(

Strange. Can you post your exe, please? I tried to build it but my 3 C settings report errors.
