The NO LOCK phrase may be specified in both formats of the READ statement. The effect of the NO LOCK phrase is described in the section The READ Statement. The placement of the phrase differs from the placement in the MF dialect, here the NO LOCK phrase immediately follows the file-name.

In a format 1 READ statement in which the AT END phrase or the NOT AT END phrase is specified, the NEXT phrase is implied and may be omitted.
