Show / ShowCenter / ShowRight (procedure)

These three commands are used to display simple text on the document. They are identical in all aspects, except in the way

they behave relative to the current margin settings: show uses the margin as a starting point to extend the string to the right;

showright uses the margin as the ending point of the string; and showcenter extends the string equally on both sides of

the margin. These commands are equivalent to print, echo or write commands in other scripting languages.

Syntax

show( text )

showcenter( text )

showright( text )

Argument

text

String value to be displayed.

Code Sample Example

This example illustrates the difference between all three variations of using the SHOW command.

Example

margin(3,1)

showright('This line is to the left of the margin')

crlf()

showcenter('This line is centered on the margin')

crlf()

show('This line is to the right of the margin')

ShowBarCode (procedure)

Note: This PressTalk command is deprecated. Use instead the barcode-specific commands.

Displays a specified string as a barcode.

Syntax

showbarcode( string )

Arguments

string

Value of type string to display as a barcode.

showbarcode needs 3 additional parameters before it can display the barcode. These parameters must be set before calling

showbarcode, using the following variables:

BarWidth
