General enquiry : I would like to add wildcard functionality to a program but have been told this is not possible and would cost a lot to get developed. A basic question i know.

Sorry a bit general- The application is in the throws of being developed. Users would like to search customer records by customer name using a wild card. This is mainly due to data quality.
Example
looking for smith
*ith
Example
looking for smith

That is indeed a tough requirement to fulfill.
If you're doing name lookup and you're dealing with primarily English names, the various soundex algorithms are quite useful for locating names that "sound" alike but are spelled differently (e.g. Smith and Smyth). The soundex algorithm generally reduces each name to a small string (4-6 characters). Using this code as a key, one can then retrieve all records with names similar to the one being searched for.
We developed a hospital patient search facility using this technique (with modifications for un-named babies, e.g. Baby Smith, sex, first initial, and birthdate/age). We've been using it quite successfully for many years to search a growing database of about 1,000,000 names.

I have a program that is similar.
Im using widows 2000 and running RM-Cobol for windows.
What I do is CALL SYSTEM USING ITEMNAME.
ITEMNAME looks like this.
01 ITEMNAME.
05 FILLER PIC X(80) VALUE
"DIR FOLDER\FOLDER\*.TXT /S/O/B > DIR.LOG'
This creates a file named DIR.LOG with the files names of all the .txt files in those folders and sub folders.
I then open this file and read it into a table and inspect
my way thu the table to search out particular file paterns.
inspect table-entry(sub) tallying tally for ALL 'ITH'. If tally > 0 then I move that table-entry(sub) to a file name
specifier and open that file. This might work for you.
Enjoy Bob
