Problems with writeln

Hi,

I need to delete some lines in a textfile. So I write the lines still needed to a new file. But some of the lines are not complete.

Example_1:
Konfigurationsdaten - Bildpfad: E:\UKH\Work\PDATA, Datenquelle: PDATA_SQLEXPRESS , Computername: PCX00000

is written to the new textfile as:
Datenquelle: PDATA_SQLEXPRESS , Computername: PCX00000

Example_2:
Patientendaten geÃƒÂ¤ndert (420): 'Metzler, Dr., Klaus: 8.12.1958, '. Alt: 'Dr.Metzler, Klaus: 8.12.1958, '

is written to the new textfile as:
Dr., Klaus: 8.12.1958, '. Alt: 'Dr.Metzler, Klaus: 8.12.1958, '

Any idea whats going wrong here?

If you could include your wln> code, that might help, but my guess is that you have not used the "result" setting in WLN>

the correct format is:

wln>FileName,result,TheDataToBeWritten

In case the write to the file encounters a problem, the "result" variable will contain a code which might indicate the problem.

As you haven't provided your code I will have to guess what the problem might be [Tip - if you want help, help us to help you and provide your code].

Anyway, if I had to guess what the problem is I'd say you've probably missed out the second parameter to WriteLn.

WriteLn takes THREE parameters:

WriteLn>filename,RESULT_VARIABLE,text_to_write

Am I right?

I forgot the result variable ....
