Yes, yes, I'd love that.  The variable "a" contains a string
afterwards, doesn't it?


Currently, I'm trying to extract some information from comments in
datafiles.  The crucial thing is that information is to be passes
from gnuplot to the script and vice versa.  I need something like

  gawkcall = sprintf("gawk -f getname %i %s", this_index, filename)
  name = execute(gawkcall)


For numerical values, you can already do this with

  getvalcall = sprintf("getval %i %s", this_index, filename)
  value = `@getvalcall`

but something like

  gawkcall = sprintf("gawk -f getval %i %s", this_index, filename)
  value = atof(execute(gawkcall))

or

  value = 0 + execute(gawkcall)

is cleaner, I think.
