Problem: History to entry line [up]...[copy]

[compsystems]

not(x>y) => y ≥ x although the sense of reading is reversed. x ≤ y (real math book print)

problem

not(x=y) => not(x==y) [up][copy][enter] NOT x=y [up][copy][enter] (NOT x)=y
x:=true; y:=false
[up][copy][enter] 0 = false // sometimes 0 other times 'false', there is no consistency

//
( e^pi = pi^e ) and (0=0) => 0 => false

Another problem

if NOT(input(id)) then kill; end;
// does not operate with NOT in lower case.
if not(input(id)) then kill; end;
