Error in DELCHR

Quivelus

Hi,


Recently i tried to use the DELCHR function. The C/Side reference guide says following:

- I am currently working in version 4 SP2

Text constants:

Text000: 'Windy Solutions'
Text001: '>%1<, is transformed to: >%2<'

C/AL:

String := Text000;
Where := '<>';
Which := 'Ws';
NewString := DELCHR(String, Where, Which);
MESSAGE(Text001, String,NewString);

It says result will be:

>Windy Solutions<, is transformed to: >indy Solution<


Why is this. I would think it should be: >Windy Solutions<, is transformed to: >Ws<. I also tried the same with: Where := '=';
This gives the same result as with Where := '<>'...

Is this a bug or am i doing something wrong?

Hej Quivelus,

The On-Line help also states that

Include...
To have the system delete any...

= Character in String that matches a character in Which. (default)

< Leading character in String that matches a character in Which.

> Trailing character in String that matches a character in Which.

That is
< removes only the leading character
> removes only the trailing character

Try using 'Windys WSolutions' => 'indys WSolution'

True,


Ok, if it works like this, then i get it. I thought '<>' stood for 'different from'.

If you want to keep 0123456789 in a string in stead of deleting them, use this:

txtCharsToKeep := '0123456789';
txtString := DELCHR(txtString,'=',DELCHR(txtString,'=',txtCharsToKeep));

My purpose was to delete all chars that where not in the string (parameter). Guess i should use another function for this purpose.

The DELCHAR(DELCHAR I wrote before just does that.

Indeed, guess i read your reply to swiftly and didn't notice the repetition of the DELCHR function. I now see how it works, tx Kriki.

P.S.: How do i close this subject? Or is this done automatically?
