I've been trying to hand code some figures in postscript, but I keep getting
limitcheck errors in flattenpath when trying to center text.  It doesn't
happen for all strings; only for longer strings.  Basically, my routine to
center text calls 'hiwi':

/hiwi {gsave newpath 0 0 moveto true charpath flattenpath pathbbox 4 2 roll
pop pop grestore} def

which returns dx dy on the stack.  When I call it as

(Non-inverting Op Amp Circuit) hiwi

I get a limitcheck.  Removing ' Circuit' from the string, it runs fine.
(I'm using 15 pt Times-Roman, but point size is irrelevant.)  Both work fine
when fed to ralpage.  The printer is a LaserWriter.

Anyone see something wrong with my code?  A workaround perhaps (other than
printing 2 strings :-) ?

Jim
