CO_BROADCAST— Copy a value to all images the current set of images
CO_BROADCASTcopies the value of argument A on the image with image index
SOURCE_IMAGEto all images in the current team. A becomes defined as if by intrinsic assignment. If the execution was successful and STAT is present, it is assigned the value zero. If the execution failed, STAT gets assigned a nonzero value and, if present, ERRMSG gets assigned a value describing the occurred error.
CALL CO_BROADCAST(A, SOURCE_IMAGE [, STAT, ERRMSG])
|A||INTENT(INOUT) argument; shall have the same
dynamic type and type paramters on all images of the current team. If it
is an array, it shall have the same shape on all images.
|SOURCE_IMAGE||a scalar integer expression.
It shall have the same the same value on all images and refer to an
image of the current team.
|STAT||(optional) a scalar integer variable
|ERRMSG||(optional) a scalar character variable
