Here, your goal is to discover the combination to the Natlands vault which, like most safes, would normally only give you three tries to get the correct code. Fortunately, a bank employee (who you're blackmailing) managed to mess with the programming of the computerized lock, so now you get 20 attempts with a progress report after each one. As an added help, his inner man also managed to figure out the format of the code, which briefly looks like this: The code has five segments, each of which consists of two symbols. The first symbol must be L or R and the second a number in the range 0 to 9. For example, L1R3L6L2RO. A progress report is provided in simple terms: white means a segment has been successfully identified; black means that one segment contains the symbols belonging to another. Be careful though, this can be quite misleading at higher levels, as the code may contain multiple segments with identical symbols. There are three difficulty levels ranging from level 1 (easiest), with no duplicate symbols in 20 moves, to level 3, possible duplicate symbols also within 20 moves, and a time limit of five minutes. When you run the program, you will be prompted to enter a level. The screen will then display the safe along with a combination panel reflecting your entry into the electronic drum mechanism. Use the keyboard for all input and to turn the sound on and off, press S. If you make a mistake, use C to cancel it. When you have decided what code to enter and display it on the panel, press Enter or Return. It only remains to wish him luck and keep an eye on the security guard. ===== List ===== * **__Listing - SAFECRAC.BAS__** 10 REM Safecracker 20 REM By Philip T Lawson 30 REM (c) Computing With The Amstrad 40 REM ------------ PCW ------------- 50 DEF FNat$(x,y,a$)=CHR$(27)+"Y"+CHR$(32+y)+CHR$(32+x)+a$ 60 DEFINT a-z:cl$=CHR$(27)+"E"+CHR$(27)+"H" 70 WHILE lev<1 OR lev>3:PRINT cl$ 80 PRINT"Enter level. 1 - Easy" 90 PRINT,"2 - Difficult" 100 PRINT,"3 - Time limit";
