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 omitted, the update starts at the
first record or row in the input file.
ordinal-record-num

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
enclose the list in square brackets.
key-spec
the alternate key tag (a 2-byte string or a 16-bit integer) designating the
