-- Option variable: setcheck Default value:
setcheck is set to a list of variables (which can be subscripted), Maxima prints a message whenever the variables, or subscripted occurrences of them, are bound with the ordinary assignment operator
:: assignment operator, or function argument binding, but not the function assignment
:= nor the macro assignment
::= operators. The message comprises the name of the variable and the value it is bound to.
setcheck may be set to
true thereby including all variables.
Each new assignment of
setcheck establishes a new list of variables to check, and any variables previously assigned to
setcheck are forgotten.
The names assigned to
setcheck must be quoted if they would otherwise evaluate to something other than themselves. For example, if
z are already bound, then enter
setcheck: [x, y, z]$
to put them on the list of variables to check.
No printout is generated when a variable on the
setcheck list is assigned to itself, e.g.,
There are also some inexact matches for
?? setcheck to see them.
