Struggle with placing element in set with tcl sript

hi,

Try replacing { } by ' '

hi 

well that doesn't work neither ..

When I select the 0 under the line of code this is writen in a pop up :

while executing
'*setvalue sets id=4 ids=elems='[hm_getmark elems 1]''
    ('uplevel' body line 1)
    invoked from within
'uplevel #0 {*setvalue sets id=4 ids=elems='[hm_getmark elems 1]'}'
    invoked from within
'interp eval $::tkcon::OPT(exec) $args'
    (procedure '::tkcon::EvalSlave' line 2)
    invoked from within
'EvalAttached $cmd'
 

I don't know what that says i can't understand this kind of language 

are you sure syntax is ... ids=elems='[... ?

or just ...ids='[...  ?

I tried many things and i'm very struggleling with the syntax but i think that the amounth of elements is way too big for being transfered from a mark to a set ( i talking about 20 000 element) so i begin to think that the problem is linked to the use of a mark for this amounth of data. I'm thinking about using a list or a table for these data but then i don't know how to feed the *setvalue with that kind of variable.

Thanks for your help tinh 

the syntax must be

*setvalue sets id=4 ids='elems [hm_getmark elems 1]'

if it is failed, try {i prefer this way}

*entitysetupdate nameofset elems 1

Man thank you so much ! The *entityupdate works !

I've been trying for two days with this single line of command haha
