Correcting 'Undefined name' error in compilation of CCL files
Question I created two CCL programs ("aprog" and "bprog") and placed them in separate CCL files of the same names ("aprog.ccl" and "bprog.ccl" respectively). I verified that both programs work correctly by themselves. Then I changed "aprog" to call "bprog" from within the code and I got an error...
