Syntax
Operand1 <> Operand2
The operands can be entered either directly or as a variable and can be of
the type Text, Number or Date/Time. The result type is always a num-
ber (1 = true, 0 = false).

"Metrohm" <> "AG" --> 1
When making a comparison between two
texts the ASCII value of the character
sequence is compared (see Chapter
2.4.4.10, page 66). Attention: Upper-
case and lowercase letters have different
values!

Operands of a different type:

1.2 <> "1.2" --> 01.2 <>

Before the relational operation, the Num-
ber is converted to Text, afterwards the
texts are compared according to ASCII
value (see Chapter 2.4.4.10, page 66).

Before the comparison, the operand is con-

Before the operation, the operand is con-
verted from the type Date/Time to Text
(here thus: "1999-10-07 00:00:00 UTC
+2"), afterwards the texts are compared
according to ASCII value (see Chapter
2.4.4.10, page 66).
