test part of fixed legnth string

stampe

Is there any way to test only part of a fixed length string

example :

myvar = text

test = copystr(myvar,1,8)

case test of
'ABC*****' :
'ABCD****' :
'ABCDE***' :

end

i'am looking for some sort of "joker" sign to use in a textstring '*' do not work

I'm afraid you can't do this in a CASE-statement.

Therefore, you have to use:

<BLOCKQUOTE><font size="1" face="Verdana, Arial">code:</font><HR><pre>
IF COPYSTR(test,1,3) = 'ABC' THEN BEGIN
END;

IF COPYSTR(test,1,4) = 'ABCD' THEN BEGIN
END;

IF COPYSTR(test,1,5) = 'ABCDE' THEN BEGIN
END;

</pre><HR></BLOCKQUOTE>

If necessary, you need to put ELSE's between the IF's, otherwise the other code gets executed also when COPYSTR(test,1,3) = 'ABC'.

Hope this helps.

You should reverse the order of the CASE checks. As shown, COPYSTR(test,1,3) = 'ABC' will be giving a match always before the other ones. So, start with the longest and work down to the shortest.
