Management
Tape File Management Utilities
The series of support and utility programs provided with CA Dynam/T permit a
wide range of functions. For instance, you can make dummy pre-assignments
to allow utility programs to take advantage of AVR. You can even convert from
other tape management systems to CA Dynam/T. The functions are discussed
later in this text.
Tape Assignment Program—TDYNASN
The TDYNASN program is designed to perform the following functions:
• Open and close files when this is not accomplished by the programs that
read and write them.
• Establish ASSGNs for tape drives before executing the program that opens
the file.
• Issue ASSGNs to dummy devices so that AVR functions can be performed.
• Equate one programmer logical unit to another.
Note: It is not necessary to use TDYNASN for CA Sort r6.1 or greater if CA
Sort has been properly generated.
