Error ................ this should be               "f SUBS".

You have told the linker to link only J2.apl and to create the
executable application called J2.  The documentation states quite
clearly that the files to be linked are read in with the "f" command
(the main application comes first).  The "o" command is like the "-o"
option with Unix compilers, it specifies the name of the output file if
it is different from the default (which is the name of the first file
read in with the "f" command).

Only if you tell the linker to find them.

It is an obsolete product.  MS has dropped it and it is now sold by the
developer, Absoft.  The current version is 2.4 I believe.
