Concatenate a string to an integer.

RA899 — Mon, 12 Feb 2024 23:43:00 GMT

Hi.

I'm trying to create new columns with the same name, but different extension.

For example, I'm trying to create column 1 & column 2 &column 3... etc.

Here is what I have:

lista = list(1 , 2, 3 , 4); 



for(i1=1, i1<N Items ( lista)+1, i1++,
 dt_limit << new column (    insert( "condition", char ( lista(i1) )  )    );

);

it doesn't seem to work, however. It either returns an error or return something like this: " condition (1, 2, 3, 4) " or: "conditionlista"

Any guidance is appreciated.

I realized I was using () instead of [] for calling the list index. It looks like its working now.

Here are a couple of ways that I typically use

Names Default To Here( 1 );

lista = List( 1, 2, 3, 4 ); 

For( i1 = 1, i1 < N Items( lista ) + 1, i1++,
	dt_limit << New Column( "condition" || " " || Char( lista( i1 ) ) );
);

Names Default To Here( 1 );

lista = List( 1, 2, 3, 4 ); 

For each( {member}, lista,
	dt_limit << New Column( "condition" || " " || Char( member ) ) );
);
