Hi, Let said I have below field value: NO. | Description 1 | help34to**solve proble(m 2 | ho23w yo44u do99ing toda y? 3 | &th@is is (very) n ice I want to turn into this: NO. | Description_2 1 | helptosolveproblem 2 | howyoudoingtoday 3 | thisisveryniceday those un-wanted characters may be all over places, I checked STRREP but I don't think length would help. any idea?This message has been edited.

You can define a custom function or simply use REPLACE But since it seems that you have a bunch of character to replace, may be complex because you will have to provide all special characters to replace
DEFINE FILE abc
newField /A250 = REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE (oldField, '1', ''), '2', ''), '3', ''), '4', ''), '*', ''), '(', ''), ')', '');
END

Thanks MartinY, this is an idea, but is there a better way to extract only 'A-Z' and 'a-z' only? WebFOCUS v8.2.06 , Windows | |||

Out of the box IBI functions are to remove/replace characters not to keep desired ones. Maybe you can accomplish that using SQL passthrough WF versions : Prod 8.2.04M gen 33, Dev 8.2.04M gen 33, OS : Windows, DB : MSSQL, Outputs : HTML, Excel, PDF In Focus since 2007 | |||

MartinY thank you for your information. I did try out using SQL function to do this and it work well, but do wish IBI can have this feature on it own, so don't have too rely on others. WebFOCUS v8.2.06 , Windows | |||

I cannot tell you But personally, I would say no. I don't think that IBI will try to implement all possible function/feature that SQL can do. Having the ability to perform SQL passthrough is the answer to be able to accomplish almost anything from SQL : especially that depending on which SQL you connect to, the functions differs. You will need to open a case and ask the question. It's only from there that you will get the right answer.

Not sure if it would help but look at the REGEX function - link T

Now, unfortunately you must read the documentation for your platform on how to make user functions. Usually, the IBI provided gencpgm.sh will create a compiled and linked program. For instance, under linux you can issue: gencpgm.sh -g -e -v -m cpgm nospchar.c Remember to issue the export IBICPG environment variable: export IBICPG= Here is a focexec that tests nospchar: DEFINE FILE CAR MYC/A15 = EDIT(COUNTRY,'9%lh9+*999999$9') ; MYD/A15 = NOSPCHAR(MYC,15,MYD) ; END TABLE FILE CAR PRINT COUNTRY MYC MYD END -RUN So, we execute it: EX TEST To get: PAGE 1 COUNTRY MYC MYD ------- --- --- ENGLAND E%lhN+*GLAND ElhNGLAND JAPAN J%lhA+*PAN JlhAPAN ITALY I%lhT+*ALY IlhTALY W GERMANY W%lh +*GERMAN WlhGERMAN FRANCE F%lhR+*ANCE FlhRANCE IBI Development | |||
