[pstricks] \listplot

[Robert Salvador]

Have a nice and not too hot day, everybody!

Are there any limitations in using \readdata und \listplot concerning  
filelength oder number of plots?
I´m always getting problems in using these commands for more than 8 oder 9  
plots in a single pspicture environment. More plots are simply not  
produced. One ... 6, 7 or 8 plots is OK.
Sometimes there is a "kind of error-message" like ghostscript 815.03  
unrecoverable error, exit code 1.
I do the 3-step latex - dvips - ps2pdf with TeXMaker to get my pdf-file.
I know this sounds a little bit "strange", but I ´ve no idea what´s going  
on here.
Maybe you can help me?

Thank you in advance.
Robert
