Negative value for StartupInfo item

[David McFarlane]

Ah, um, well, I think you are stuck, at least if the KB article, 
http://www.pstnet.com/support/kb.asp?TopicID=1268 , is to be 
trusted.  You see, StartupInfo parameters set to data type Numeric 
are limited to non-negative values from 0 to 32,767, the largest 
signed integer that will fit in 16 bits.  This is an oversight on the 
part of the designers of E-Prime, as 16-bit signed integers may also 
encode values from -32,768 to -1, but the code automatically 
generated to handle StartupInfo parameters explicitly prohibits 
negative values (don't take my word for that, just look at the 
generated code in the Main() routine).

This may have been fixed in EP2.0.10.182 -- as I recall, numberic 
StartupInfo parameters in the new release are now Long (32-bit) 
integers, but I do not know whether it still peversely prohibits 
negative values.

For all I know you could work around this by declaring the RandomSeed 
StartupInfo parameter as data type String, and then hope that EP does 
the automatic type conversion for you.  I leave that as an exercise for you.

Or, give a shout to PST Web Support at 
http://support.pstnet.com/e%2Dprime/support/login.asp and see what 
they say -- and then, please post their response back here for everyone.

But as I will explain shortyly in an update to your other thread, 
none of this may help you anyway.
