I have been using statements like this for years without a problem

write(txt, t = 2, h = sy/12, rotate = 270, center=true);

The new release says that "t"," h", "rotate", and "center" are not
specified as a parameter.  I guess that means "specified as a parameter
in the definition of the module that is being called".

The comments in the "write" library include the following:

// These control the default values for write() writesphere() writecube()
// if the parameters are not included in the call. Feel free to set your own
// defaults.

//default settings
    center=false;
    h = 4;             //mm letter height
    t = 1;             //mm letter thickness
    space =1;             //extra space between characters in
(character widths)
    rotate=0;            // text rotation (clockwise)
    font = "Letters.dxf";    //default for aditional fonts

So, that library clearly understand the concepts of "h", "t", etc.  On
the other hand, the definition of write() is simply

module write(word){

I am confused.  Were there parameters like "rotate" in some version of
the "write" library?  Are there still, but the syntax has changed so
that I am clueless?  Has anyone else encountered these warnings before? 
Should I be using some other library instead?  The number of warnings is
large enough that I would entirely miss a new warning should it appear
at some point.

Thanks!

Unfortunately 'write()' uses a unique 'feature' of how parameters are
implemented, whether it is technically kosher is a debate to be had.

When you call any module, and parameters in the call are instantiated as
local variables.

module a() { echo(i=i,j=j); }

a(i=1,j=2);

Compiling design (CSG Tree generation)...
WARNING: variable i not specified as parameter, in file
openscad-2019.06.17.ci2847, line 3
WARNING: variable j not specified as parameter, in file
openscad-2019.06.17.ci2847, line 3
ECHO: i = 1, j = 2

So you want to add t/h/rotate/center as positional parameters to the write()
module definition with those defaults.

There is also a edit/preference/advanced option to turn off that check.

and you could use the top level variables to define the local defaults

module write(word, h=h, t=t, rotate=rotate, center=center, space=space,
font=font) {...}

MichaelAtOz said "There is also a edit/preference/advanced option to turn off

It would be helpful if I could turn this on and off on a per
source-code-file basis.  That is, for files where I know there are spurious
warnings, I would like to turn the warnings off; but for the rest of my
code, I would like to leave them enabled.

Is there a way to control this in the source code for a particular 3D
design?
