John,

gen x = . replace x = y if y == z (note the "==" in the if clause) Best Christoph Engel Am 7/15/2012 4:59 PM, schrieb Steve Nakoneshny:

John, At first glance, it would seem that -gen x = y if y = z- would serve as a solution. Of course, this assumes that your I'd vars are numerical and not string vars (which they probably should be stored as).

I'm looking to create a variable x which is equal to y, but only if the given value for y can be found in another variable, z. These are all id numbers, so say y is a universal id and z is a mother's id, telling you the universal id of the mother in relation to the child. For example: yzx 1.. 2.2 3.3 42. 5.. 6.. 737 8.. 9.. 107. So I'm trying to figure out how to create x. Any help would be much appreciated.
