How to delete the entire 'Row' when the cell is blank/empty ?

There is no need to use an IF() clause in the deleting of the rows with missing values.

// If checking for a character column
dt << delete rows(dt<<get rows where(:link==""));

// If checking for a numeric column
dt << delete rows(dt<<get rows where(isMissing(:Quantity)));

YEAH, I agree with @txnelson , if you really wanna do this by using if, you can do like below

Names Default To Here( 1 );
dt = Open( "$sample_data/big class.jmp" );

total_rows = N Row( dt );

For( i = total_rows, i >= 1, i--,
	If( :age[i] == 14,
		dt << delete rows( i );
		wait(0.5) // wait for a while to let you see the delete action
	)
);

or you can do this:

Names Default To Here( 1 );
dt = Open( "$sample_data/big class.jmp" );

dt << Select Where(Is Missing(:column_you_want_to_check));
dt << Delete Rows;
