I have some constants as well as macros to be defined for PostScript.

pstVerb

{   

  /a {3} def

  /b {2} def

}

There are three possible places:

• In the preamble (A).


• In document but outside pspicture (B).


• In pspicture (C).

documentclass[border=15pt,pstricks]{standalone}

% A

begin{document}

% B

begin{pspicture}[showgrid](-4,-4)(4,4)

% C

psellipse(0,0)(!a b)

end{pspicture}

end{document}

For option A and B, I got unnecessary white spaces as follows.

But for option C,

documentclass[border=15pt,pstricks]{standalone}

begin{document}

begin{pspicture}[showgrid](-4,-4)(4,4)

pstVerb

{   /a {3} def

/b {2} def

}%

psellipse(0,0)(!a b)

end{pspicture}

end{document}

the white spaces no longer exit.

You can it use where you want, but you have to pay attention that you do not
overwrite existing definitions. /a and /b are already defined in several ways
for internal functions.

Use always variables with at least two letters or use an own dictionary:

documentclass[border=15pt,pstricks]{standalone}

pstVerb{   

    /aA 3 def

    /bB 2 def

}

pstVerb{

  /myDict 2 dict def % define a local dictionary with two variables

  myDict begin

    /a 3 def

    /b 2 def

  end

}



begin{document}

begin{pspicture}[showgrid](-4,-4)(4,4)

    psellipse(0,0)(! myDict begin a b end )

    psellipse(0,1)(! aA bB )

end{pspicture}

end{document}

For C it works braces pspicture holds all local.

  I was using PSTricks for several years to create many graphics. However, the possibility of a local dictionary is complete new to me. This is very useful to avoid conflicts with internal commands already defined. Thanks!
