STX instructions for outputting texts
Function DisplayText(Dev:Int,
Pos:Int,
Const Ref Text:String);
Parameter Value Description
Dev 8 ... 11 Number of the device on which the
text is to be output
Pos Not relevant Will not be evaluated
Text Text to be output Constant text, or name of a string
variable
To output a text on a printer module, the instruction must be invoked as
follows:
DisplayText( 8 , 0 , 'Hello World !' );
DisplayText( 8 , 0 , StringVar);
The first instruction causes the printer module to output the text 'Hello World!'.
Then, the second STX instruction causes the content of the string variable
StringVar to be output.
The task in the application program stops at the instruction
DisplayText()
until the whole text has been output.
Function DisplayText2(Dev:Int,
Pos:Int,
Const Ref Text1:String,
Const Ref Text2:String);
Parameter Value Description
Dev 8 ... 11 Number of the device on which the
text is to be output
Pos Not relevant Will not be evaluated
Text1 Text to be output Constant text, or name of a string
variable
Text2 Text to be output Constant text, or name of a string
variable
To output one text out of two texts on a serial interface module, the instruction
must be invoked as follows:
DisplayText2( 11 , 0 , 'Fehler:', 'Error:' );
The STX instruction causes either the text 'Fehler:', or 'Error:' to be output on a
serial interface module. MR 2806 lets you control which text will be output.
The task in the application program stops at the instruction
DisplayText2()
until the whole text has been output.
