COPY Command

066374 Tandem Computers Incorporated 3–5

PURGE

deletes an existing file from the destination subvolume

having the same name as <output file>. The <output file>

replaces the deleted file. If this option is not used and a file

exists with the same name as <output file>, PCFORMAT

terminates with an error message.

Examples

The COPY command provides three ways to designate a database file for

conversion: (1) entering a COMINT ASSIGN command prior to the

PCFORMAT COPY command, (2) using the DATAFILE option in the COPY

command, and (3) specifying only a <record name> that identifies the file.

Examples of all three methods are included under the heading “Running

PCFORMAT” in Section 2.

Note The DATAFILE option has the highest priority for specifying a database file, followed by a

COMINT ASSIGN command, and then <record name>. In other words, if both the

DATAFILE option and COMINT ASSIGN command are used with one COPY command, the

file named by DATAFILE is used. Only when DATAFILE and COMINT ASSIGN are not

used is the file named in <record name> used.

Dictionary in Current

Subvolume

Normally you can save keystrokes by selecting the subvolume containing

the database dictionary prior to entering the COPY command. This is

particularly true when you plan to enter more than one COPY command

for the same dictionary.

Unless otherwise specified with the DICTIONARY option, the COPY

command assumes the database dictionary is in the current subvolume. For

example:
