Is there a way to update a field in a record knowing the field name and value

Given a Record:

MyRecord = record
    Company: string;
    Address: string;
    NumberOfEmplyees: integer;

can you write a function call like

function UpdateField(var FieldName: string; FieldValue: variant): bool;

so that:

UpdateField('Company', 'ABC Co');

would update MyRecord.Company to 'ABC Co'?

I looked for an example but everything I found is for a database. Any help pointing me in the right direction is appreciated.

Thanks, Charles
