n is a value between 1 and 255 that is less than or equal to the length of the
FIRST KEY specified.
COUNT num-records
the number of records or rows to update.
If omitted, all records are copied
EXACT
sets exact positioning on the record key (primary or alternate) specified in the
FIRST KEY option.
FIRST { ordinal-record-num }
{ KEY { record-spec | key-value } }
{ key-spec ALTKEY key-value [, key-value ] }
the starting record of the input file to update.
If FIRST is omitted, the update starts at the first record or row in the input file.
ordinal-record-num

KEY { record-spec | key-value }
the primary key value for the starting record or row of a structured disk file.
record-spec is a fixed quantity limited to 2**63 -1.

for unstructured files, record-spec is the starting relative byte address

for relative files, record-spec is the starting record number

for entry-sequenced files, record-spec is the 64-bit numeric record key
key-value applies only to key-sequenced files and specifies the
approximate position of the starting record; key-value is specified as a
string or as integer byte values in the range of 0 to 255.
The key-value is entered as follows:
"[" { string } [, { string } ] "]"
{ 0:255 } [ { 0:255 } ]
where the integers represent the byte values. To specify a list of strings,
enclose each string in quotation marks separated by a comma, and
