For Instring-manipulation other languages allowing direct adresing of string positions are better suited.
Perhaps code in C and call as .Fll.
In vfp manipulating the "substrings" as records or array elements (see optional parameter to alines()) is best

>Kindly guide how to append records in the above case, is there any other easy less time consuming way of changing value in the string at once without appending records in cursor and going through the process of Scan-Endscan and re-writing the entire file with new values (i.e the numeric value just before every 'p')
