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!

NAME
|
|
saveval - enable or disable saving of values
|
|
|
|
SYNOPSIS
|
|
saveval(arg)
|
|
|
|
TYPES
|
|
arg any
|
|
|
|
return null value
|
|
|
|
DESCRIPTION
|
|
When evaluation of a line of statements at top level starts, a
|
|
"saved value" for that line is assigned the null value. When saving
|
|
is enabled (the initial state) and a statement being evaluated is an
|
|
expression or a return statement, the value returned by that expression
|
|
or statement replaces the current saved value; on completion of
|
|
evaluation of the line, the saved value, if it is not null, updates
|
|
the "oldvalue".
|
|
|
|
This saving of values is enabled or disabled by calling saveval(arg)
|
|
with an argument arg that tests as nonzero or zero,
|
|
|
|
Whether saving is enabled or disabled does not affect the operation of
|
|
eval(str).
|
