how to write data to a file with a custom format?

Dear Mathcad users,

Would anyone know how to write data to a file with a custom format?

After mathcad calculation, I am trying to write columns of data1 and data2 into an external ascii file in the following format:

( data1, data2)

How do you insert "(" and "," and ")" before, in between and after the data?

Any help would be appreciated!

Thanks,

HJS
