DoForm (procedure)

Runs the current document. This command is usually issued once a complete data page has been received and committed to

buffer. This command should only be used before reading the next page of data from the input stream. It is strictly for use

within a User-Define Emulation.

Syntax

doform()

Argument

None

Code Sample Example

This example is an extract from a user-defined emulation. The search() command looks for a formfeed and adds its line

number. The line number is stored as a string and the document is run. The data page is cleared and the search is over.

Example

search(&str,'\014')

set(&current.line,&current.line + 1)

store(&current.line,&str)

doform()

clearpage()

endsearch()

GetNextDataPage(procedure)

Advance to the next data page of the sample data file. Note that this command may have unpredicted behavior if not used cor-

rectly in documents that use a user-defined emulation.

This command should only be executed when printermode is not in design mode. The result will be incorrect on screen, but

there will be no

unexpected behaviors. Therefore, the only solution is for end-users to make sure the command doesn't get executed while in

Design mode by bracketing it within a if(&printermode<>0) ... endif()

structure.

Syntax

getnextdatapage()

SetDataPage(procedure)

Specify the data page of the sample data file.

Syntax

setdatapage( pagenum )
