Just for clarity, my problem was not that I couldn't change the value of x and 
xx.
My problem was that \tfx and \tfxx behave differently than \tfa \tfb etc.
I expected that \tfx and \tfxx change the font size to x and xx size compared to
the default/normal size and not compared to the currently used/environment
font size. According to the reference manual that would be the expected 
behavior. 
The reference manual [pages 106-107 (108-109 pdf pages)] writes:

"Besides these two-letter commands, there is a series of font selector commands 
with a
size suffix attached. Some examples of that are:
\tfx \bfx \slx \itx
\tfa \tfb \tfc \tfd \tfxx
The a suffix selects a somewhat larger font size than the default. Each of the 
ordered
alphabetic suffixes a, b, … select a somewhat larger actual font than the 
previous suffix. The x and xx suffixes select smaller and yet smaller versions. 
Note that these commands select font sizes relative to the default, not 
relative to whatever font size is currently in effect."

I don't see how the fixed values for x and xx is related to this.

Best regards,

bcsikos

Many thanks for the tip, Hans.

Many thanks for your reply, Hans.

Now I understand why it happens.

Dear list,

from the previous message from Csikos, I have generated the following
sample:

\setupbodyfontenvironment[default][a=5, x=8, xx=6]
\starttext
Default {\tfa Larger} {\tfx Smaller1} {\tfxx Smaller1} \\
Default \tfa Larger \tfx Smaller2 \tfxx Smaller2
\stoptext

I can set a different value for a, but not for x or xx. The values for x
and xx seem to be hardcoded.

If this isn’t a bug, what am I missing here?


that the x/xx sized are automatic adaptions of tf bf sl it ..., so: \bf 
\tx is the same as \bfx:


test {\bf \tx test} test {\bfx test}

but using \tx is more flexible (as it adapts)

The default sizes (12pt, 11pt etc.) have fixed values for x and xx, you
can see them in font-pre.mkiv:

\definebodyfontenvironment
  [\!!twelvepoint]
  [\s!text=\!!twelvepoint,
 \s!script=\!!ninepoint,
   \s!scriptscript=\!!sevenpoint,
  \s!x=\!!tenpoint,
 \s!xx=\!!eightpoint,
\v!big=\!!fourteenpointfour,
  \v!small=\!!tenpoint]


Wolfgang,

many thanks for your help. I was reading that file.

I know that a simple workaround would be to set the font size another
value, but why do x and xx fixed values and not a, b, c and d?

I mean (I’m only trying to understand), why are only those two values
(form the letter series) fixed?


because they are the text counterparts of the smaller math sizes (those 
are fixed too) ... think of \high and \low usage

Dear list,

from the previous message from Csikos, I have generated the following
sample:

\setupbodyfontenvironment[default][a=5, x=8, xx=6]
\starttext
Default {\tfa Larger} {\tfx Smaller1} {\tfxx Smaller1} \\
Default \tfa Larger \tfx Smaller2 \tfxx Smaller2
\stoptext

I can set a different value for a, but not for x or xx. The values for x
and xx seem to be hardcoded.
