\unprotect
\input pstricks

and therefore when ConTeXt sees \ifx!#1 it thinks that \ifx! is a
csname. Adding a space after \ifx avoids that.

As I said in my previous message, this is easy to fix at ConTeXt end
defining an appropriate catcode regime before inputing pstricks.

So, the pstricks package does not need to be changed, but the ConTeXt
code that is calling the package needs to be adapted.

ok, understood.

thanks,
Herbert
