is a pleasant enough read, had some useful information.

Interesting..

So I wrote a very difficult program in DF20 and can you guess what the output is?



Use Windows.pkg


Procedure CompareTest
String sString1
String sString2


// ſecret == secret == Secret
Move "ſecret" to sString1
Move "Secret" to sString2

If (Lowercase(sString1)=Lowercase(sString2)) Begin
Showln "PASS"
End
Else Begin
Showln "FAIL"
End
inkey windowindex
End_Procedure


Send CompareTest

His article was good, but he did not mention that all of those nuances are managed by the COLLATING algorithm ...

If case matters,
if accented mattes,
if ...
if ...

yes, there are a LOT of ifs...

If you want those "special" chars to be considered the same. you have to tell it to do so... and now DF can do it.. (oh my God, )

Try this one now..


Procedure CompareTest2
String sString1
String sString2

Set_Attribute DF_LOCALE_CODE to "en_US@colStrength=primary"

// ſecret == secret == Secret
Move "ſecret" to sString1
Move "Secret" to sString2

If (sString1 = sString2) Begin
Showln "PASS"
End
Else Begin
Showln "FAIL"
End


End_Procedure


Send CompareTest2


inkey windowindex

:rolleyes:

And notice that I dont even need to use lowercase function anymore..

Cheers

Ah.. forgot to get even further....



Procedure CompareTest2
String sString1
String sString2
String sString3

Set_Attribute DF_LOCALE_CODE to "en_US@colStrength=primary"

// ſecret == secret == Secret
Move "ſecret" to sString1
Move "Secret" to sString2
Move "secret" to sString3

If ((sString1 = sString2) and (sString1 = sString3) and (sString2 = sString3)) Begin
Showln "PASS"
End
Else Begin
Showln "FAIL"
End


End_Procedure


Send CompareTest2


inkey windowindex

Thanks Samuel,

I was wondering about that, but too much other stuff (not DataFlex) going on down here at that moment to research in detail.

For others wondering about DF_LOCALE_CODE, see this post: https://support.dataaccess.com/Forums/showthread.php?65401-Congratulations-about-ICU-addoption-request-to-not-stop-there!&p=351649#post351649
