Both Output index & output indexes used for "Conditional assignment" of your input data to out ports but the only difference is Output_index allows to assign to only 1 output port whereas Output_indexes allows to assign to multiple output ports.

********************************* Eg 1 **********************************

out::output_index(in)=

begin

out:1:if ( in.country=='Malaysia') 0 ; // if country name is Malaysia then divert input records to out0 port

out:2: if (in.country--'Singapore') 1;

out:: 2;

end;

**************************** Eg 2 **********************

out::output_indexes(in)=

begin

out:1:if ( in.country=='Malaysia') [ vector 0,1] ; // if country name is Malaysia then divert input records to out0 & out1 ports

out:2: if (in.country--'Singapore') [ vector 2 ];

out:: [vector 3 ];

end;
