3 years ago I was thinking that the form function could be replaced by a Jupyter notebook running J. The mark up could be used to delineate the Form the user is putting together. The user would just enter manually what is going on in the section heading. From a cursory view of the Form function it is trying to capture just that. A Jupyter note book would capture a J language session in a savable format and you just need to start a new notebook page for each musical piece you want to design
Chapter 10 page 134 of Cybernetic Music FORM is a function that captures APL (J in our use case) commands. It does so in a musical outline structure. As a section of music can have subsections. FORM tries to capture the commands to produce that subsection of music. The interface is dated and this function may be one of the last to be implemented so that a more modern interface can be applied
