Re: [OpenSTA-users] empty strings passed as parameters cause all parameters to be ignored.

[Bernie V. <Ber...@iP...>]

Hi Stephen,

Its a bug. I tried a simple subroutine with 4 string args. As soon as one 
(counting from left to right) is set to "", then all remaining arguments are 
set to "" or 0 if numeric. Looks like the code that parses arguments passed 
to subroutines quits when it see's a null. I would definitely report it on 
sourceforge.

If you need an urgent resolution, please read more at 
http://www.iperformax.com/services.html and

All the best,
