How this error generate?

when I do hspice simulation, after hspice netlist complied
there many error :

Init: hspice initialization file: /opt/synopsys/hspice/2002.2.2/hspice.ini

**error**: o or i follows a number on a line could
be a bad character as component unit

If I remember rightly, you can't have a net or subckt name which begins with number,
except (in the case of numbers) if they are wholly numerical. It's bad practice
anyway, because this is a common restriction in many tools - and I think it's
a restriction with hspice (I may be wrong and these days it may be different),
but that's what the error message suggests to me.
