Dear Experts

I am using VFP6, I have a table, entitled master, fields as

code c(7)
detail c(40)

Both fields are charcter type.

To show the data of this table I use a grid.

In the first column of grid I want to show code field in the following format

1401-001
1601-005
1802-155

What and where inputmask or format should I apply?

Please help me
