This section documents the various system parameters which can be used to control the operation and behaviour of the PostScript interpreter. Most parameters handle the memory allocation. For example the maximum memory that can be allocated by the font cache. The PRISMAsync supports the system parameters mentioned in the ‘PostScript Language Reference Manual, Third Edition’.
