+** 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
+**
