Changes
GSX
,/* Example */ Driver source code
GSX consists of:
* GENGRAF.COM
* ASSIGN.SYS
* GSX.SYS
* Device drivers (e.g. DDMODE0.PRL)
Make your GSXprogram like any other .SYS - The device independent part of COM file. Then use GENGRAF.COM to configure it for GSX. Now run the resulting COM file which will start GSXand then your code.
e.g. A>GENGRAF GSXDEMO.COM A>GSXDEMO.COM == Drivers and ASSIGN.SYS ==
Vendors provided platform specific drivers which implemented GSX.
Amstrad/Locomotive provided DDMODE0.PRL, DDMODE1.PRL and DDMODE2.PRL which implement drivers for each of the CPC's screen modes. ASSIGN.SYS is a text file which must exist along side gsx.sys and which contains the mapping of device id to the driverthat implements that GSX device. When you program GSX you open a device by its id. Example content of ASSIGN.SYS
