Is there a way to input a multi-selection-checkbox of arbitrary length? (SOLVED)

Hello,

So, what you are really looking for is a way to programaticaly create your variable list, both for storing the values AND for the INPUT command...

Why not try:

EXPORT BS()
BEGIN
LOCAL COMETS:={"ALL","Halley","Lewkowicz","The rest"};
LOCAL LST:=MAKELIST(0,I,1,SIZE(COMETS));
LOCAL OKC,UTP;
LOCAL TTL:={"//"};
LOCAL HLP:="HH";
local l2= MAKELIST({'LST(I)',1},I,1,SIZE(COMETS));
OKC:=EVAL(EXPR("INPUT("+STRING(l2)+",TTL(1),COMETS,HLP,1,1)"));
END;

The INPUT command needs both the NAME of the variable and their values...
This is why INPUT does NOT evaluate its first parameter, if it did evaluate it, then it would NOT be able to get the variable name that it needs...
As a result, it is NOT possible to use a programmatic way/method to generate that first parameter, because recalling it, is an evaluation, which does not happen...
Hence the use of a string there to generate the TEXT of the INPUT statement and then the conversion from text to an expression, which is then evaluated...
