This U03_SimulationAndGamingWithAPL_setup.readme contains instructions for setting up Tomas Gustafsson's demo from APL Seeds '21. It appears on the APL Seeds '21 webpage and in the U03_SimulationAndGamingWithAPL.zip file. The 3D rendering engine DLL that Tomas supplies can only be run in 32-bit Dyalog on Microsoft Windows. We have, therefore, made available a special 32-bit version of Dyalog v18.2 for Windows, which should be used only in conjunction with this demo. These instruction assume that you download U03_SimulationAndGamingWithAPL.zip into c:\tmp and extract the contents of the zip file into c:\tmp. 1. Download this setup.readme and follow the instructions. 2. Download and install Dyalog 18.2 Unicode 32-bit from the APL Seeds '21 webpage. You do not need to enter a serial number as this is for demo purposes only. 3. Download U03_SimulationAndGamingWithAPL.zip from the APL Seeds '21 webpage and extract the contents. 4. Copy dyalog.exe.config from "C:\tmp\U03_SimulationAndGamingWithAPL\demo21" into C:\Program Files (x86)\Dyalog\Dyalog APL 18.2 Unicode 5.

Assuming that the downloaded mtv3d64_8.dll is in C:\tmp\U03_SimulationAndGamingWithAPL\demo21, change the current directory to that before running the program. That is: ]CD c:\tmp\demo21 )LOAD .\demo21 sim1.sim
