I have rows in a file which each one has 20 fields. At the 15th column of each row I need to do some insertions of special characters
x;x;x;x;x;x;x;x;x;x;x;x;x;YYYYY;x;x;x;x;x;x
x;x;x;x;x;x;x;x;x;x;x;x;x;YYYYY;x;x;x;x;x;x
could become
x;x;x;x;x;x;x;x;x;x;x;x;x;||YYYYY||;x;x;x;x;x;x
x;x;x;x;x;x;x;x;x;x;x;x;x;||YYYYY||;x;x;x;x;x;x
How could I do this?
