Andrei,

If your version of 'caget' and 'caput' is built from the 
epics/extensions/src/EzcaScan directory. You should be able to use 
the caget and caput to get the waveform record.

On a UNIX system, you have to include the

 /usr/local/epics/extensions/bin/$HOST_ARCH in your search 'path'
 /usr/local/epics/extensions/lib/$HOST_ARCH in your 'LD_LIBRARY_PATH'
 
where 
	$HOST_ARCH is 'solaris'       for EPICS 3.13 
	$HOST_ARCH is 'solaris-sparc' for EPICS 3.14

If your 'path' and 'LD_LIBRARY_PATH' environment is not correctly set, 
you will have problem with caget and caput. May be you should ask 
your system adminstrator automatically set these up for EPICS users.
