Running the Perl or Python Program
Before running the Perl or Python program, make sure that you included the absolute path of
the Perl or Python wrapper script (hpnvs.pl or hpnvs.py) in the program file:
• On Windows:
hpnvs-installation-directory\nvscript\bin\hpnvs.pl
or
hpnvs-installation-directory\nvscript\bin\hpnvs.py
hpnvs-installation-directory is the directory where you installed the Neoview
Script software files. For more information, see Table 2-1 (page 34).
• On Linux or UNIX:
hpnvs-installation-directory/nvscript/bin/hpnvs.pl
or
hpnvs-installation-directory/nvscript/bin/hpnvs.py
