Could you please explain how this -gen mage = age[mlineno]- works or where I
could find it. I realize that square brackets are used for explicit

For a particular record, the _value_ of the variable mlineno is substituted, so that f.i. when mlineno records the value of 2 (mother's record is the second in line) the righthandside becomes age[2], meaning the value of age from the second record (being the mother).
