Yes, there are several ways to pass parameters into a PS program.

The most obvious would be to concatenate the definitions in front of the
program text and then execute the whole thing. This way will work on ANY ps
interpreter.

Or you can use ghostscript's "code" option:

  gs -c '/param1 12 def' prog.ps

Or ghostscript's "define" options:

  gs -dPARAM -dPARAM1=12 -sSTRING=string prog.ps

Or ghostcript's "argument-passing" option

  gs -- prog.ps arg0 arg1 arg2

which predefines '/ARGUMENTS [ (arg0) (arg1) (arg2) ] def' before executing.
