[SIC\]DEFINE ALIAS AliasName TargetVar [/GLOBAL]
Define a new variable AliasName pointing towards (a subset of) an exist-
ing variable. The new alias shares all the properties of its target:
type, Local or Global status, Readonly attribute. The TargetVar can be a
sub-array, but implicit transposition is not allowed.
If the /GLOBAL option is present, the TargetVar must be a Global vari-
Aliases can be deleted using the standard DELETE /VAR command: this does
not delete the TargetVar variable. On the contrary, when a standard
variable is deleted, all aliases attached to it are also deleted, since
the variable content disappears.
Structures cannot have aliases, but structure members can.
