Tests and logic

Comparisons that return 1 or 0, AND, OR, XOR, NOT and SAME.

16.1The TEST menu#

Comparison commands take two objects and return 1 for true or 0 for false. Right shift MODE opens TEST. You can also type the symbols with the keys: left shift 4 types <, left shift 5 types >.

TEST page 1: ==, ≠, <, >, ≤, ≥. The display shows: RAD { HOME } / 6: / 5: / 4: / 3: / 2: / 1: / == ≠ < > ≤ ≥ .
TEST page 1: ==, ≠, <, >, ≤, ≥.
TEST page 2: AND, OR, XOR, NOT, SAME, TYPE. The display shows: RAD { HOME } / 6: / 5: / 4: / 3: / 2: / 1: / AND OR XOR NOT SAME TYPE .
TEST page 2: AND, OR, XOR, NOT, SAME, TYPE.
