Notes about the AGC file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The AGC file type is primarily associated with 'AfterGRASP' by John Bridges. AfterGRASP is a multistage compiler that produces a tight stack-based language based on FORTH with a LISP-like syntax.
