replacing character in a string when position is a variable

Hello, Does anyone have a little routine that performs replacing a character in a string based on position number which is a variable.(TABLE FILE).
I have string "0000000000" and need to replace single 0 with 1 based on S_POS value (between 1-10).

Thank you, Mila

Mila,

Look into using substr within your own function. You could pass the source field and the position and return the actual string output. If you use this function several times then it would be well worth your time. Something like (pseudo code) -

FUNCTION REP_ZERO(srce_field, position)
src_length = LENGTH(srce_field);
REP_ZERO = SUBSTR(src_length, srce_field, 1, position - 1, position -1, 'A'||(position - 1)) || '1'
           SUBSTR(src_length, srce_field, position + 1, src_length - position, 'A'||(position - 1)) ;
END

I am sure that someone like Alan or Francis will be along any minute now to flesh it out, but it would help you considerably to look at the help files and work it out.

Here I am standing at the Focal Point booth in Cash Vegas Smiler using Kathleen's Id (I'm sure she won't mind the extra karma point Wink), ably supported by Prarie, Carol Dobson, FrankDutch and GamP.

We are not sure that STRREP would satisfy this requirement as the need is to target a particular position within the string and if you have all zeroes how would you be able to use STRREP? You would end up changing them all?

Jim, you may not be here, but your presence is sorely missed Razzer

How about using OVRLAY

TABLE FILE CAR
PRINT COUNTRY
      COMPUTE
      S_POS/I1 = LAST S_POS  + 1 ;
      REP1/A10 = OVRLAY(COUNTRY, 10, '1', 1, S_POS, 'A10') ;
END


Waz...

You could also use a combinations for functions and use the EDIT function to replace the position you want EDIT(xxxx, '9999999919999...');

Thank you all of you
The OVERLAY works perfectly.

My documentation on functions does not specify that variable can be used here. Probably it is outdated.

Waz,

Good call on the OVRLAY, there's always one function easily forgot. Just goes to show why having documentation to hand is soooo important.

Nubi,

Cash Vegas is a "nickname" for Nashville TN (as in Johnny Cash). I've also heard it called Nash Vegas and other, not so pleasant, terms Wink

... and that post takes you into the Virtuoso karma bracket. Well done for reaching the 1000 Smiler

And achieving it whilst at Summit must be a first Razzer
