SAS was originally based on PL/1, and having programmed in PL/1,=20
I'm inclined to use the PL/1 symbol for not equals, which is the
^=3D (actually it is not the caret on IBM mainframes, but the not symbol
which looks like L on its side). =20

Subject: Re: '^=3D' and '~=3D'?
Maybe good reason to use mnemonic equivalents.
882 data _null_;
883 a =3D .v MIN .z;
884 b =3D .v MAX .z;
885 ax =3D .v >< .z;
886 bx =3D .v <> .z;
NOTE: The "<>" operator is interpreted as "MAX".
887 c =3D .A NE .A;
888 put (_all_)(=3D);;
a=3DV b=3DZ ax=3DV bx=3DZ c=3D0
