 ...penstroke routine deleted...

BUT here comes the problem:

>1 inch 4 inch moveto
>/Helvetica findfont 1 inch scalefont setfont
>(TESTING) false charpath penstroke

According to my laserprinter (TI2115) and the PS red book: (page 192)
If <charpath> was used to construct any portion of the current path,
<pathforall> is not allowed; its execution will produce an 'invalidaccess'
error.

Who can invent a routine <penstroke> alike, but working with fonts?
May be something can be done with defining a new font on basis of 
an existing font.
