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.
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 varations 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)
Displays a specified string as a barcode.
Syntax
showbarcode( string )
Arguments
