There is a cool option of dropping one graph from multigraph (after that it goes as separated one). How to get  this dropped structure itself? I.e. i have "graph" component with command AllPlots that itself is

AllPlots:=plots[display](AllPlotsStructure,...);

AllPlotsStructure is a list of plot/textplot.

After all i removed one structure by drag-and-drop on component. How to update AllPlotsStructure correctly?

Need to do in maple smth like that:

Have s:={'a', 'b'};

a:=4;

naturally s[1] resolves to 4. Moreover, eval(s[1],1)=4, so s successfully should forget about a.

But...

a:='a'; and s[1] returms... again a.

So, why dereferencing of pointers  is not the same as 'eval 1-level' resolving?

How actually can i unassign 'a' having s only?

Or (not obviously, but same!) related question:

how to obtain s1:={'a', 'b'} having s={a,b} with nonresolvable a and b .i.e. eval(smth, -1)?

evalhf: more than 500 locals

From where that restriction is? Is it workaroundable?

For next list of variables 

RVars:=[[''Rla'',''Rlb'',''Rsa'',''Rsb'',''RN''], [''GAL'',''GBL'',''GAS'',''GBS'',''GN'']];

(no double qoutes, 2 single quotes, of course)

want all of them to be redefinable with suffix option i.e. both of operators below

assign(m || (RVars[1,1]), 5);

assign( RVars[1,1], 5);

should be reentered without restart as many as wish. With 2nd form everything...
