SETMODE Procedure
The SETMODE procedure is used to set device-dependent functions. For ADCCP,
you will probably only need SET MODE 30, if you need other SET MODE functions,
Refer to the System Procedure Calls Reference Manual for a complete list of the
SETMODE function codes.
A call to the SETMODE procedure is rejected with an error indication if incomplete
nowait operations are pending on the specified file.
CALL SETMODE ( filenum !i
, function !i
, [ parameter-1 ] ) !i
filenum input
INT:value
is the number returned by the OPEN call that opened the line and identifies it as
the file to receive the SETMODE function .
function input
INT:value
is an integer value that specifies the desired SETMODE function. I/O operations
are allowed to finish in any order when function has a value of 30.
parameter-1 input
INT:value
is a subcode used in conjunction with function to further define the desired
mode setting operation. For a function value of 30, parameter-1 is as
follows:
Value Description
0 I/O operations are not allowed to
complete in any order (default) .
1 Allow I/O operations to complete in
any order
If parameter-1 is set to 1, nowait operations do not necessarily finish in the order in
which the I/O process returns them. (Operations that finish in time for AWAITIO
to collect their output return in the order issued.)
