I forgot to include this in my previous message. Sorry. I'm on a Mac, and I save my workspaces in ~/Documents/APL/workspaces/ (apparently GNU APL automatically puts WSs in the workspace dir) "~/" is "/Users/myaccount/" on Macs.
When I cd into "APL/" then start GNU APL and do ")LOAD wsid", I get this error message: )load EULER =================================================== Assertion failed: level >= 0 in Function: read_Function_name in file: Archive.cc:2257 Call stack: ---------------------------------------- -- Stack trace at Archive.cc:2257 ---------------------------------------- 0x0 @@@@ 0xa @@@@ 0xa @@@@ 0xa @@@@ 0xa @@@@ 0xa @@@@ 0xa @@@@ 0xa @@@@ 0xa @@@@ 0xa @@@@ 0xa @@@@ 0xa @@@@ 0xa @@@@ 0xa @@@@ ======================================== SI stack: Depth: 4 Exec: 0x7fc1b0c13d40 Safe ex: no Pmode: ◊ ~2 FIB 5 PC: 0 =================================================== Assertion failed: idx < items_valid in Function: operator[] in file: ./Simple_string.hh:140 Call stack: *** do_Assert() called recursively *** =================================================== *** immediate_execution() caught other exception *** Right now I can do ")COPY wsid", and it works fine, but I have to rename it and overwrite the previous one each time. Any insight? Again, best regards, Louis
