gD a1 a2 [a3 .. aN]       where a1 a2 [a3 .. aN] are set variables

gD`mtm~ a1 a2 [a3 .. aN]

gD/mtm~ a1 a2 [a3 .. aN]

gD

When specified by itself then the operation is performed on the object on top of the stack and the one that is one below it, then the result is pushed on the stack

●  Operator gD gets the subgroups and the elements symmetric difference

Use the operator gD to get the symmetric difference between datasets represented by set variables.

 

gD EXAMPLE
In the following example we want to visualize the subdirectories and files contained in each directory without being found in any other directory. We start ASPL loading the sample workspace WS1 and issue the command gD on the set variables.

 

gD OPERATION

# aspl WS1
    (start ASPL loading the sample workspace WS1 )

①  aspl> v
    (print the symbol table showing the set variables)

②  aspl> gD a1 a2
    (get the group symmetric difference between a1 a2)

③  aspl> gD a1 a2 a3
    (get the group symmetric difference between a1 a2 a3)

④  aspl> gD a3 a4 a5
    (get the group symmetric difference between a3 a4 a5)

 

● Tickable Predicates for gD

This gD is tickable with predicates that are shown in the following table:

       a yellow note
gD`_  gets the subgroups and the elements symmetric difference 
gD`c=  gets the subgroups and the elements symmetric difference such that they have the same checksum 
gD`c~  gets the subgroups and the elements symmetric difference such that they have different checksums 
gD`c~~  gets the subgroups and the elements symmetric difference such that they have all over different checksums 
gD`h=  gets the subgroups and the elements symmetric difference such that they have the same entropy 
gD`h~  gets the subgroups and the elements symmetric difference such that they have different entropies 
gD`h~~  gets the subgroups and the elements symmetric difference such that they have all over different entropies 
gD`mtm=  gets the subgroups and the elements symmetric difference such that they have the same make time 
gD`mtm~  gets the subgroups and the elements symmetric difference such that they have different make times 
gD`mtm~~  gets the subgroups and the elements symmetric difference such that they have all over different make times 
gD`ks=  gets the subgroups and the elements symmetric difference such that they have the same ksum 
gD`ks~  gets the subgroups and the elements symmetric difference such that they have different ksums 
gD`ks~~  gets the subgroups and the elements symmetric difference such that they have all over different ksums
