(Get the code!)
Setting a variable to an empty string would not be a problem even without a separate command, because "" is different from NULL:
Empty string:
epicsEnvSet "var",""
Delete:
epicsEnvSet "var"
(Work for both vxWorks shell and iocsh.)
But I will implement epicsEnvUnset because it is the cleaner interface.
