GSX
From CPCWiki - THE Amstrad CPC encyclopedia!
GSX is the standard graphics library for CP/M.
GSX consists of:
GENGRAF.COM - This takes a .COM file and configures it for use with GSX. The resulting .COM file can be run without GENGRAF.COM and launches GSX before running your code.
ASSIGN.SYS - This is a text file which contains the mapping of devices to driver files that implement them.
DDMODE0.PRL - An example of a driver.
GSX.SYS - The device independent part of GSX.
Drivers
Vendors provided platform specific drivers which implemented GSX.
ASSIGN.SYS is a text file which must exist along side gsx.sys and which contains the mapping of device to driver.
