VERIFY
Compares the contents of the tofile with the contents of the fromfile,
record by record, immediately after a copy operation. The two files must
reside on either disk or magnetic tape and must have identical record
characteristics, that is, record size, format (fixed, variable, or
undefined), and type (ASCII or binary).
The VERIFY function is essentially the same as the COMPARE function,
except that VERIFY is always performed in conjunction with the copying of
a file, whereas COMPARE is not.
Syntax
;VERIFY [=number-of-errors]
Where:
number-of-errors Is an integer specifying the number of errors after
which the operation terminates. If this parameter
is omitted, the default is 1.
File Attributes
Both the fromfile and tofile must be a disk file or a magnetic tape file.
The fromfile must have read access, and the tofile must have read/write
access.
Operation
Each time FCOPY detects an error while verifying files, it prints a
message on the standard listing device (your terminal in a session or a
printer in a job). The message specifies the number of the fromfile
record in which the error occurred.
Restrictions
You cannot use VERIFY with the CHAR, CLEAR, KANA, OCTAL, HEX, or HEXO
functions.
Examples
In the example below, FCOPY copies the disk file OLDFILE to the disk file
DCOPY and then compares the two files, record by record. If FCOPY finds
an error, it prints a message on the standard listing device and
terminates the operation.
>FROM=OLDFILE;TO=DCOPY;VERIFY
In the example below, FCOPY copies a file from the magnetic tape *TAPE2
to the magnetic tape *TAPE6 and then rewinds the two tapes and compares
them record by record. Each time it finds an error, FCOPY prints a
message on the standard listing device. The tenth error terminates the
operation.
>FROM=*TAPE2;TO=*TAPE6;VERIFY=10
