Make Valid hook

Use this hook to adjust the field's value before it is checked. You can use it for example to round a field's value.

Example:

function extern long tcibd001.dsca.make.valid(long mode)
{
        |* Always start with capital
        tcibd001.dsca(1;1) = toupper$(tcibd001.dsca(1;1))
        return(0)
}
