EZY Prolog reading/writing subsystem follows PDC Prolog conventions.

File should be opened for reading (openread) or writing (openwrite/openappend) and current reading or writing device should be established.

EZY Read/Write has 2 predefined symbolic files:

• screen - for writing into Messages Window of the Prolog Console

• stderr - for writing into Trace Window of Prolog console

EZY Read/Write supports only 7 simultaneously opened files (for reading or writing).

Programmer can switch between opened files by use of readdevice/writedevice

File should be closed after use
