$G[ET] ( glvn )

This form returns the value of the specified glvn depending on its state, defined by $Data(glvn). The following cases are defined:

  1. $D(glvn)#10 = 1
    The value returned is the value of the variable specified by glvn.
  2. Otherwise, the value returned is the empty string.

$G[ET] ( glvn , expr )

This form returns the value of the specified glvn depending on its state, defined by $Data(glvn). The following cases are defined:

  1. $D(glvn)#10 = 1
    The value returned is the value of the variable specified by glvn.
  2. Otherwise, the value returned is the value of expr.

Both glvn and expr will be evaluated before the function returns a value, so that the behavior of this function with respect to the naked indicator is well defined.
