Have you tried to display the string A in Scilab?

-->PATH_IMAGEMAGICK = "c:\Path\to\Imagemagick"
  PATH_IMAGEMAGICK  =
  c:\Path\to\Imagemagick

// This is probably not what you want:
-->A = 'PATH_IMAGEMAGICK + ''\convert -delay 50 '
  A  =
  PATH_IMAGEMAGICK + '\convert -delay 50

// You probably want this:
-->A = PATH_IMAGEMAGICK + '\convert -delay 50 '
  A  =
  c:\Path\to\Imagemagick\convert -delay 50
