Has anybody been able to code a generic-search-and-replace function ?

-*
-* Replace occurances of P2 in P1 with P3
-*
DEFINE FUNCTION SREPLACE/A255(P1 A255, P2 A255, P3 A255)
...
...
END

I was about to implement it but fell short of how finding out syntax to
write a loop in webfocus. I dont see in manuals how to write a loop. Any
ideas ? I see that the DM kind of GOTO is not supported in functions.

Working on WebFOCUS 7, we can use STRREP function:

STRREP Function: Replacing Character Strings
(documented as 7.1.3 new feature)

Simple D.M. Example tested with WF 7.1.0 & 7.1.1:
-SET &V1 = 'a OR b OR c OR d OR e' ;
-SET &V2 = STRREP(&V1.LENGTH, &V1, 4, ' OR ', 1, ',', &V1.LENGTH, 'A&V1.LENGTH');
-TYPE V1= &V1
-TYPE V2= &V2

Output:
V1= a OR b OR c OR d OR e 
V2= a,b,c,d,e

Regards,
Mikel

I tested it just now on 5.3.3 and yes it worked. Thx for the tip. That helped me avoid a whole bunch of coding.

Hi,

I think that the above function work only when you know the length of each value of the string. What is the solution if I get a string as input and want to apply find and replace method. Please let me know.

Thanks

How about using LENGTH function to first find lengths ?

-SET &V1 = 'ABCDEFGH';
-SET &L1 = &V1.LENGTH;

What's actually interseting about the example is that the output is wrong.

When you use FTOA it left justifies the text it creates.

Also the substitution is invalid because all of the columns are not
the same number of characters, so you end up with 
 
      USD 123456
      USD 12345


If it was correctly justified it would look like

 
      USD 123456
       USD 12345



A floating $ is wrong, the example would only work if the format of the field
is Dt.sN
