The Sands of Egypt

The Sands of Egypt is an adventure game written by James Garon, Ralph Burris, and Steve Bjork of Datasoft for the TRS-80 Color Computer. It was licensed to Tandy Corporation and was the first disk-only game for the Color Computer sold by RadioShack. Ports to the Atari 8-bit family in 1982 and Apple II in 1983 were published by Datasoft. Set in 1893, the game follows a British explorer and archaeologist who is lost in the desert. Text commands are entered in the lower half of the screen, while a sometimes animated image of the current location is displayed in the upper half.
Gameplay.
The player interacts with the game by typing commands, either in a "VERB NOUN" format or single words such as codice_1 for "move north". The number of moves made is tracked as the score. It can be seen with the codice_2 command. The player needs to periodically drink water to stay alive.
Reception.
Owen Linzmayer, reviewing the Color Computer original for "Creative Computing", wrote "In comparison with other adventures, "The Sands of Egypt" does feel a bit shallow" and "the game relies strongly on perseverence and patience." In "Electronic Games", Tracie Forman didn't mention the puzzles, but wrote "By far the most striking thing about "The Sands of Egypt" is its eye-pleasing animation" and called it "an exceptional gaming experience."
In a walkthrough of part of the game for "TRS-80 Microcomputer News", Bruce Elliott discussed the codice_3 command:
