This APL
tree type is used to
represent program parts that represent function applications. E.g., if a program
contains the text f(1,2,3)
than this text will be parsed towards
an APL
tree whose name is f
and whose Arg
part is a TAB
representing (1,2,3)
. Another possibility
for APL
is that it represents function applications of the form f@x
.
Of course, in this case the argument is not a TAB
, but a VAR
.
The name is accessed by the APL_NAM_idx
index. The arguments table
is accessed by the APL_ARG_idx
index.
