Does anybody have information on DOS interrupt 21H function 52H which changes the values of ES and BX to point to some sort of table with presumably lots of useful information therein? Also, anybody ever heard of interrupt 2AH or, better yet, know what it does? If you're curious, I found each of these used within the code for ASSIGN.COM. BTW, it's not documented as such but ASSIGN remains resident after you invoke it. (So should I load it before SIDEKICK? :-) ) Please respond via mail. ------------- -- Jay Elvove ..!seismo!mimsy!jay
