2.4.4 Variables
Overview
Variable types
The following types of variable are differentiated:
Name/Syntax
Description
Method variables
'MV.Variable name.Variable identifier'
Method variables are variables that are defined in the
START
command.
Command variables
'Command name.Variable identifier'
Command variables are variables that are generated by the
individual commands in the method sequence. The com-
mand variables are shown in the order in which the com-
mands are carried out in the method sequence.
Result variables
'RS.Result name.Variable identifier'
Result variables are special command variables that are
generated by
CALC
commands and are available under their
own name.
Determination variables
'DV.Variable identifier'
Determination variables are general variables and cannot be
assigned to individual commands.
System variables
'SV.Variable identifier'
System variables are general variables and cannot be as-
signed to individual commands or determinations.
Common variables
'CV.Variable name.Variable identifiere'
Common variables are method-independent variables that
are accepted from the table in the configuration at the start
of the determination (see Configuration - common vari-
ables).
Entering variables
Variables must always be entered enclosed by inverted commas
'
(e.g.
'MV.MyVariable'
).
Note
When using variables it is essential that their data type (
Number
,
Text
or
Date/Time
) is taken into account.
Method variables
Method variables are variables that are defined in the
START
command of meth-
ods. The data type (
Text
,
Number
,
Date/Time
) of the variables can also be adapted
there. These variables can be either sample data variables (
Sample size
,
Sample
size unit
,
Sample position
,
ID1...ID8
, appear in the Run window of the Workplace) or
are assigned values. In the
Variables
field of the Formula editor all the
Method vari-
ables
available for the current method are listed according to their sorted com-
mand name.
Syntax
'MV.Variable name.Variable identifier'
Examples:
'MV.TestDate', 'MV.RestTime.VAL', 'MV.TestValue.OVF'
In order to avoid syntax errors the method variables can be selected di-
rectly in the Formula editor under
Variables/Method variables
.
