As-Easy-As
As-Easy-As for DOS and As-Easy-As for Windows was a shareware 32-bit spreadsheet program developed in the mid-1980s for MS-DOS and later for MS Windows. The name is a play on the phrase "as easy as 1-2-3", a reference to the dominant MS-DOS spreadsheet at that time, Lotus 1-2-3 with which it competed with for a fraction of the contender's price. The program was sold by Trius, Inc. (Not to be confused with Tritus, the makers of the Tritus SPF clone of the mainframe ISPF interface and editor.)
