[Coco] Run Time Error 203 "Illegal Mode"

[Rick Ulland]

Just spitballin', I guess scheduling and would try eliminating the 3 
sequential forks to shell. Don't touch, just delete the temp file from 
inside B09 (DELETE "pathname"), and since 'ls' is an external program, 
maybe waste a little time inside B09 so the SHELL ls  command can wrap 
up and close the file before you OPEN read mode.
