+** Source: test1.c

+** Purpose: Tests the PAL implementation of the feof function.
+** Open a file, and read some characters. Check that
+** feof states that it hasn't gone by the EOF. Then
+** read enough characters to go beyond the EOF, and check
+** that feof states this is so.
+**
+** Depends:
+** fopen
+** fread
