I tried to make a program to print some data on _exact_ positions with postscript. Because we want to work with centimeters, i define:
/cm {28.3 mul}
further, i try to move to the wanted position:
13.7 cm 24.8 cm moveto
and my ghostscript complains:
Error: /undefined in cm Operand stack: cm --nostringval-- 13.7
...
what am i doing wrong?
Thank you Koen Breugelmans

It needs to read like this:
/cm {28.3 mul} def

>> /cm {28.3 mul}
