Forming the Final XFD Name

From the starting name, the final name is formed as follows:

The compiler removes any extensions from the starting name
It constructs a universal base name by stripping out directory information that fits any of the formats used by the operating systems that run the compiler
It reduces the base name to eight characters and converts it to lower case
It appends the letters .xfd to the base name

Examples of XFD names

COBOL code	File name
ASSIGN TO "usr/ar/customer.dat"	customer.xfd
SELECT TESTFILE, ASSIGN TO DISK	testfile.xfd
ASSIGN TO FILENAME	(you specify)
