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

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
