Every >> in Glicol must sit between two nodes; a trailing or orphaned >> is a syntax error

The >> operator in Glicol connects exactly two nodes: one on its left and one on its right. A trailing >> at the end of a chain, or a lone >> at the start of a line, is a syntax error that prevents the graph from updating. When editing a chain, the most common cause is accidentally deleting the final node while leaving the operator behind. The fix is always to remove the dangling >> or complete it with a valid node.

Examples

saw 110 >> — syntax error (trailing >>). Fix: saw 110 >> mul 0.2.

Assessment

Given the Glicol line saw 110 >> lpf 800 >>, identify the error and write the corrected line.
