When making a comparison between two
texts the ASCII value of the character
sequence is compared (see Chapter 2.4.4.10,
page 81). Attention: Uppercase and low-
ercase letters have different values!

Before the relational operation, the Number
is converted to Text, afterwards the texts are
compared according to ASCII value (see
Chapter 2.4.4.10, page 81).
