Operating System Trigger by Powerhouse error number

HP3000, os 6.5 , powerhouse 8.19.c2
we are currently using stream job on daily transactions  processing. my
question is:-

Can we identify   errors from Powerhouse QTP programs at Operating System
level  by error number or  system variables or  any identifier?  Example of
errors are as below :

'Data access error' or
'Data conversion error' or
'Data is full'

I intend to trigger some other processes if the above errors occur in the
stream job.
