Help for LABEL

LABEL is a VICAR program, designed for both interactive and batch
use, which can be used to create, remove, list, and modify in
various ways the labels in a VICAR file.  It is designed to replace
all old IBM VICARlabel processing programs (LABCAT, VLABEL etc.) and
add additional capabilities.

When LABEL is invoked on the command line, the mode of operation
is determined by the subcommand which is used.  For help on the
subcommands and the general operation of LABEL, type TUTOR LABEL.
Limitations:  The VICAR label items are in the form of "keyword = value".
If the value is of the string type, there is a limitation on the maximum
string length depending on the operating systems.  At current time, the
maximum string length is limited to 132 characters, including white spaces 
(the Solaris OS constraint).  Users need to be aware the program does not 
warn users if the maximum string length is exceeded.
