character creation: DM in promotions

[Michael Lewis]

What is DM in the promotion field in careers?

[Panther Al]

Dice modifier:

Basically saying if you meet the preconditions (Say, Intel 7 or higher) you add a certain number to your roll. So, say you need a 6 for promotion, you roll a five. No promotion for you... unless you have that Intel 7, in which case you add one to the five, and get six: and the promotion.

thanks.

I couldn't find what that meant.
