[NTG-context] new upload

[Hans Hagen]

Hi,

I uploaded a new lmtx ... not much done due to the heat (entered reading 
mode instead) but ... apart from some work in progress ... we now have 
some basic bitwise operations (maybe we need some more). So far we have:

\startlines
\meaning\bitwiseset
\meaning\bitwisenot
\meaning\bitwisenil
\meaning\bitwiseand
\meaning\bitwiseor
\meaning\bitwisexor
\meaning\ifbitwiseand
\stoplines

used as:

\scratchcounter = \bitwiseand "01      "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwiseand "01 with "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwiseand "03      "02 
\uchexnumbers{\scratchcounter} \par

\scratchcounter = \bitwiseor  "01      "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwiseor  "01 with "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwiseor  "03      "02 
\uchexnumbers{\scratchcounter} \par

\scratchcounter = \bitwisexor "01      "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwisexor "01 with "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwisexor "03      "02 
\uchexnumbers{\scratchcounter} \par

\scratchcounter = \bitwisenil \bitwisenil "0F "02 "01 
\uchexnumbers{\scratchcounter} \par
\scratchcounter = \bitwisenil \bitwisenil "0F with "02 with "01 
\uchexnumbers{\scratchcounter} \par

\scratchcounterone\zerocount

\scratchcounterone \bitwiseset "FFFFFFF
\ifbitwiseand      \scratchcounterone "8000000 YES \else NOP \fi
\ifbitwiseand      \scratchcounterone "F000000 YES \else NOP \fi
\ifbitwiseand      \scratchcounterone "1000000 YES \else NOP \fi
\scratchcounterone \bitwisenot \scratchcounterone
\ifbitwiseand      \scratchcounterone "8000000 YES \else NOP \fi
\ifbitwiseand      \scratchcounterone "F000000 YES \else NOP \fi
\ifbitwiseand      \scratchcounterone "1000000 YES \else NOP \fi

\scratchcounter \bitwiseand "01 "02
\scratchcounter \numexpr    "01+"02\relax

\ifcase      \bitwiseand \scratchcounterone \plusone \else \fi
\ifbitwiseand            \scratchcounterone \plusone \else \fi
\ifnum                   \scratchcounterone=\plusone \else \fi

A while ago I played with bitwise operator sin \numexpr but in the end 
removed that because it's messy with the symbols to be used, but I will 
look at that agaon if needed.
