Number Text Number 2 <= "1.2" --> 01.2 <=
"Metrohm" --> 1 Before the relational operation, the Num-
ber is converted to Text, afterwards the
texts are compared according to ASCII
value (see Chapter 2.3.4.10, page 65).
Text Number Number "Metrohm" <= 1.2 --> 0 The same rules apply here as for the previ-
ous operation.
Number Time Number 2.0 <= Time(1999;10;07) -->
1 Before the comparison, the operand is con-
verted from Date/Time to a Number.
Time Number Number Time(1999;10;07) <= 2.0 -->
0 The same rules apply here as for the previ-
ous operation.
Text Time Number "Metrohm" <=
Time(1999;10;07) --> 0 Before the operation, the operand is con-
verted from Date/Time to Text (in this
example: "1999.10.07"), afterwards the
texts are compared according to ASCII
value (see Chapter 2.3.4.10, page 65).
Time Text Number Time(1999;10;7) <=
"Metrohm" --> 1 The same rules apply here as for the previ-
ous operation.

The operands can be entered either directly or as a variable and can be of
the Text, Number or Date/Time type. The result type is always a num-
ber (1 = true, 0 = false).

Text Text Number "Metrohm" <> "AG" --> 1 When making a comparison between two
texts, the ASCII value of the character
string is compared (see Chapter 2.3.4.10,
page 65). Attention: Uppercase and
lowercase letters have different values!
Time Time Number Time(1998;04;06) <>
Time(1964;02;03) --> 1 (see Chapter 2.3.4.6.2, page 53)
