The IDLffDICOM::GetChildren function method is used to find the member element references of a DICOM sequence. It takes as an argument a scalar reference to a DICOM element representing the parent of the sequence.
Syntax
Result = Obj->[IDLffDICOM::]GetChildren(Reference)
Return Value
Returns an array of references to the elements of the object that are members of that sequence. The scalar parent reference is possibly obtained by a previous call to GetReference or any method that generates a reference list. Any member of a sequence may also itself be the parent of another sequence. If the scalar reference argument is not the parent of a sequence, the method returns -1.
Arguments
Reference
A scalar reference to a DICOM element that is known to be the parent of a DICOM sequence.

FOR j = 0, N_ELEMENTS(children)-1 DO $
BEGIN
PRINT,children[j]
