Eq: =

One may wish to do conditional processing dependent upon whether two numerical expressions are equal or not.  The form of the syntax that can be employed in such a case is

Terma eq termb

or

Terma = termb

where eq or = can be used interchangeably.  Examples from formconditional.gms

If(x eq 2, z=2);

Eq1$(x=2)..  zz=e=3;

Loop(I$(sqrt(x)+1 = y+2),z=z+1)
