VAR. - Variable Set Value/Clear

MiniRobotLanguage (MRL)

VAR. Command

VARiable set value or clear

Intention

This command can be used to assign a Value to a Variable.

There are three forms, please look at the examples.

The VAR.-command makes a complete variable-resolution, this includes any special-folder or system-variables on the value-side.

Therefore it may be a bit less efficient then the VAB. command, which does not make a variable resolution.

There is an "Implicit VAR."-Command, from the preprocessor, if you just omit the VAR. and write:

$$AAA=12

§§BBB=99

In this case, the Preprocessor will just add the "VAR." in front of the Line for you. Therefore at runtime the Line would look like this:

VAR.$$AAA=12

VAR.§§BBB=99

To get a complete resolution of the target side, including formulas, you can use

Syntax

VAR.[P1]=[P2]

Parameter Explanation

P1 - Variable-name

P2 - Value that will be assigned to the variable. If P2 is omitted,

the variable will be set to empty.

Example

'This will clear the variable:

VAR.$$ABC=

' This will assign the variable a value or string and replace all special-folders

' and systemvariables:

VAR.$$ABC=Hallo

' This will assign a Value without Specialfolder-Processing

: $$ABC=Hallo
