Susan,

You need merely change [CueSize] to [F_CueSize] on BlockHeader and 
the program works.  I will make that trivial change with EP1.2 and 
send that to you separately, perhaps you can then forward it on.

Thanks for the explanation of the added complexities that that 
program was meant to address.

As for "non-script" comments, my own recent brainstorm is to insert 
inline code in some places for the sole purpose of adding comments to 
explain the program.  E.g., at the start of each SessionProc I now 
regularly put an inline code object called "ReadMe" where I write a 
brief description of the program as a whole, add any needed 
implentation notes, date, author, and version notes, and a running 
list of dates & version changes.  I find this solves a lot of 
problems for me, (which is why this is standard practice in any 
conventional programming environment).  I am ashamed however that it 
took me almost a decade of using E-Prime to come upon this simple workaround.
