Lt: <

One may wish to do conditional processing dependent upon whether one numerical expression is less than another or not.  The form of the syntax that can be employed in such a case is

Terma lt Termb

or

Terma < Termb

where Lt or < can be used interchangeably.

Examples from formconditional.gms

If(x Lt 2, z=2);

Eq4$(x<2)..  zz=e=3;

Loop(I$(sqrt(x) < y+2),z=z+1)
