Some folks might think: “you still use RCS”?!? And we will say, hey, at least we switched from SCCS to RCS back in … I think it was around 1994 ... at least we are keeping up! :-) :-) :-) Logs say that SCCS version 18 became RCS version 19 on 1994 March 18. RCS served us well. But now it is time to move on. And so we are switching to git. Calc releases produce a lot of file changes. In the 125 releases of calc since 1996, when I started managing calc releases, there have been 15473 file mods!

SYMBOL and NAME
|
|
-> - arrow operator
|
|
|
|
SYNOPSIS
|
|
p -> X
|
|
|
|
TYPES
|
|
p pointer to an lvalue
|
|
X identifier
|
|
|
|
return lvalue
|
|
|
|
DESCRIPTION
|
|
p->X returns the same as (*p).X. Thus the current value of *p is
|
|
to be an object of a type for which X identifies one element.
|
|
p->X then returns the lvalue corresponding to that element of the
|
|
value of *p.
|
|
|
|
The expression *p.X will cause a runtime error since this is
|
|
interpreted as *(p.X) in which p is expected to be an object of
|
|
an appropriate type.
|
|
|
|
Spaces or tabs on either side of -> are optional.
|
|
|
|
EXAMPLES
|
|
; obj pair {one, two}
|
|
; obj pair A, B
|
|
; p = &A
|
|
; p->one = 1; p->two = 2
|
|
; A
|
|
obj pair {1, 2}
|
|
|
|
; A->two = &B
|
|
; p->two->one = 3; p->two->two = 4
|
|
|
|
; *p->ptwo
|
|
obj pair {3, 4}
|
|
|
|
; B = {5,6}
