Emulation, Data File, and Data Pages

ClearPage (procedure)

Clears the current data page and loads the next one. 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 and generally follows DoForm (procedure).

Syntax

clearpage()

Argument

None

Example:

This example the default User-Defined Emulation that corresponds to a Line Printer data file.

search(&str,'\014')

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

store(&current.line,&str)

doform()

clearpage()

endsearch()

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

store(&current.line,&str)

if(ge(&current.line,&current.lpp))

doform()

clearpage()

endif()

DefineData (procedure)

Change the active data file to the one specified in the path parameter.

Changing the data file in the middle of document processing can have unexpected consequences and should only be

used if you understand the implications of doing so.

Syntax

definedata( path )

Argument

path

String value specifying the path of the data file.
