The WAIT Statement

H1001 wait-stmt	is WAIT ( wait-spec-list )
H1002 wait-spe	is UNIT = io-unit or ID = scalar-default-int-expr or ERR = label or IOSTAT = label

• A wait-spec-list shall contain exactly one UNIT= specifier, exactly one ID= specifier, and at most one of each of the other specifiers.

The WAIT statement terminates an asynchronous data transfer. The IOSTAT= and ERR= specifiers are optional and are described in sections 9.4.1.4 and 9.4.1.5, respectively.

Advice to implementors.Implementors may choose to implement any or all asynchronous I/O synchronously. This essentially means using the ID= clause on the data transfer statement to record the results of the transfer, then supplying the results to the matching WAIT statement. (End of advice to implementors.)
