This snippet behaves differently in the interpreter vs a J code file:
$ jconsole
lcd =: 3 : ' (4!:4<''lcd'') { 4!:3 $0 '
COMMON_SCRIPT_PATH =: ;}:}:;:>lcd''
COMMON_SCRIPT
/Applications/j64-701/system/main/
$ cat jlib.j
#!/usr/bin/env jconsole
lcd =: 3 : ' (4!:4<''lcd'') { 4!:3 $0 '
COMMON_SCRIPT_PATH =: ;}:}:;:>lcd''
echo COMMON_SCRIPT_PATH
exit ''
$ ./jlib.j
/Users/andrew/Desktop/src/mcandre/j/./
This is unfortunate because I was planning to use the snippet as part of a
Makefile that would install my J package when a user enters "make install".
