How do I concatenate variable column name with a string?

Muhu — Sat, 10 Jun 2023 23:32:51 GMT

This is what I have:

for ( k = 1, k < selColumn, k++,
ColumnName = selColumnNames[k];
dt << New Column( dt:ColumnName );
);

This what I want:

for ( k = 1, k < selColumn, k++,
ColumnName = selColumnNames[k];
dt << New Column( dt:ColumnName || "Mean" );
);

selColumnNames is a list of all the column names in my table.

I was able to solve it, here is the code:

for ( k = 1, k < selColumn, k++,
ColumnName = "Mean_" || selColumnNames[k];
dt << New Column( ColumnName );
);
