Zadana velikost slozenych zavorek/METAPOST

[Josef Polách]

Zdravim vsechny, 

Byl tu resen problem natahovacich zavorek v LaTeXu. Potrebuji naopak udelat 
slozenou zavorku o presne zname vysce. V TeXu jsem si upravil definici podle 
TBN, str. 341 takto:

\catcode`\@=11
\def\n at space{\nulldelimiterspace=0pt \m at th}
\def\Biggg#1{{\hbox{$\left#1\vbox to 40pt{}\right.\n at space$}}}
\catcode`\@=9

V normalnim plainovskem textu mi to funguje korektne, staci napsat \Biggg\} a 
mam ji tam -- jenze tu svorku potrebuji dostat do METAPOSToveho obrazku a 
kdyz napisu toto:

label.bot(btex
\catcode`\@=11
\def\n at space{\nulldelimiterspace=0pt \m at th}
\def\Biggg#1{{\hbox{$\left#1\vbox to 40pt{}\right.\n at space$}}}
\catcode`\@=9
$\Biggg\}$ etex,z101);

nebo toto:

label.bot(btex
...
$\mathclose\Biggg\}$ etex,z102);

tak mi to mpost nebere a krici neco o nedefinovanych ridicich sekvencich. 
(error log je úplně na konci) -- jako by se vzpiral tem zavinacum... 

Takova vec treba funguje korektne: 
label.bot(btex $\mathclose\Bigg\}$ etex,z102);
jenze ta zavorka je pro mne prilis kratka :(

Nebo se da nejak nejak v METAPOSTu zvetsit ta "obycejna" zavorka?

Co jsem zasklil? Co delam spatne? Priznam se, ze METAPOST se teprve nesmele 
pokousim dobyvat a mozna jsem prehledl neco elementarniho...

BTW: Resili jste nekdo v METAPOSTu umisteni textu podle krivky? 

Dekuji za radu a preji hezky den

Pohoda

Josef

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
