Parameter Description Example
PDF The PDF reference returned from DynaPDF.New. $pdf


Returns 1, 0 or error.


Whether we have a working document.
If an error occurred it is not always clear whether the PDF file was already deleted or if it is still in memory. Therefore, this function can be used to determine whether a PDF file is still in memory.
If an open PDF file is in memory the return value is 1. If no open PDF file is in memory the return value is 0.

See also HaveOpenDocument function in DynaPDF manual.


Save PDF only if we have a document and there was no error:

If [ MBS("DynaPDF.HaveOpenDocument"; $pdf) ]
    Set Variable [ $PDFData ; Value: MBS("DynaPDF.Save"; $pdf; "hello.pdf") ]
    Set Field [ Create Text::PDF ; $PDFData ]
End If
