Example
Below, you will find several examples of how different formatting instructions affect the
representation of a current value:
Current value Formatting instruction Output
( corresponds to a blank)
16#F4 in address VB0 %VB0:1.0I% -12
16#F4 in address VB0 %VB0:6.0I% -12
16#F4 in address VB0 %VB0:6.3I% -0.012
16#0C in address VB0 %VB0:2.0H% 16#0C
16#0C in address VB0
(16#00 for the next byte)
%VW0:4.0H% 16#000C
16#0C in address VB0
(16#00 for the next 3 bytes)
%VD0:8.0H% 16#0000000C
Examples of formatting for placeholder information in e-mails
Note
Integers with sign (format element I) and unsigned integers without sign (format element U)
can be interpreted as fixed point decimal numbers.
Example:
VD100 contains the fixed point number for the value to be interpreted 12345dec.
If the placeholder %VD100:2.3U% is used for this value in an e-mail, this value is transferred
in the e-mail as 12.345.
Calculation: Result = value / (10^number of desired places after the decimal point) → 12.345
=12345/10^3
Note
Received e-mails may also contain #### in the placeholder instead of the expected value.
This always happens when a placeholder could not be filled with a value that conformed to
the formatting instructions.
