When a column formula is created by an encrypted script, the formula is also encrypted. If you want the formula to be visible, you can decrypt only the formula using the Eval (Parse) function. For example, if the following script is encrypted, the formula for weight is encrypted in the Formula Editor:
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt << New Column( "Encrypted",
		Numeric,
		Continuous,
		Format( "Best", 12 ),
		Formula( :weight * 2 )
	);
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt << New Column( "Not Encrypted",
		Numeric,
		Continuous,
		Format( "Best", 12 ),
		Formula( Eval( Parse( ":weight * 2" ) ) )
	);
