\hspace variations

\hspace variations

[Vyatcheslav Yatskovsky]

Hello,

I have some problems with \hspace. I try to insert it between two 
images, and this is what I get
1) \hspace{1cm} or \hspace<1cm> gives space  but writes "1cm" betwen images;
2) \hspace[1cm] does not work at all
3) \hspace[big] works fine, but \hspace[2*big] does not

I want to get space twice as big, but how?

Best,
Vyatcheslav

\definehspace[2*big] [2\emspaceamount] % [1] name [2] dimension

\starttext

A big big \hspace[2*big] space.

\stoptext


In this case '2*big' is the name of that skip, not the dimension value.
See core-spa.tex for definitions of \hspace, \definehspace and
\hspaceamount.

Best wishes, Peter

Thank you, Wolfgang, for your solution. Seems like \hspace cannot take 
numeric values at the moment, only predefined constants like "big". 
Maybe it is reasonable to include your code below into context core files?

Meanwhile, I used "\hskip 2cm", it worked fine.
