Syntax: N_SPLITA(<variableC>)

Returns alias-> portion of variable name.

Example

? N_SPLITA("cust->ssno")
  CUST
? N_SPLITA("company")
  <null string>
? N_SPLITA("m->mssno")
  M

Notes

N_SPLITN analyzes only the string passed as an argument.  It does not verify
that a field or variable of that name actually exists.

The alias clause is returned without the "->" connecter.
