From column: Enter the column number at which to test for the string. This box appears when you select On line at
column, On previous line at column, or On next line at column in the Location box. Recall that these options are not avail-
able in database emulation.
When advanced condition is true
This box appears when you select When advanced condition is true in the Line condition box.
Line displays if: Enter the PlanetPress Talk expression that defines the line condition. Remember that a condition,
and thus this expression, must always resolve to either True or False.
4. Define whether or not you want the document to display a blank line when the line condition resolves to False for a
given line (or record).
Do not display a blank line when condition is false: Select to prevent a blank line from appearing when the
line condition resolves to False. Clear to display a blank line when the line condition resolves to False.
5. This completes the line condition definition. If you have no other adjustments to make in the Data Selection properties
dialog box, click OK to exit the dialog box.
To create a line condition using the Object Inspector:
1. Select the data selection object on which you want to set a line condition.
2. In the Object Inspector, locate the Line condition properties and adjust them to create the line condition you want to set
on the object.
To remove a line condition using the Data Selection properties dialog box:
1. In the Structure area or in the Page area, double-click the data selection object.
2. In the Data Selection properties dialog box, click Lines.
3. In the Line condition box, select No line condition.
4. If you have no other adjustments to make in the Data Selection properties dialog box, click OK to exit the dialog box.
To remove a line condition using the Object Inspector:
1. Select the data selection object from which you want to remove a line condition.
2. In the Object Inspector, locate the Line condition property and select No line condition.
Examples of Line Conditions
You might use a line condition to accommodate an unstable data page structure. For example, consider a document that uses
ASCII emulation and for which the data selection you want does not always appear in exactly the same place on every data
page; the data selection shifts up or down by a few lines. The string “PREF” appears on those data lines, making it possible to
uniquely identify them. You create a data selection object that spans the entire area in which the data selection can appear,
and set a line condition to test for the presence of the string “PREF.” The data selection applies only to those lines in the data
selection region that contain the string “PREF.”
PlanetPress Supports Global Variables in the Global Function Library Manager
To view global variables in the Global Function Library Manager:
l In the PlanetPress main menu, choose Tools | Application | Global Function Library Manager.
In the Global functions in the current document column, global variables are sorted first followed by global functions in alpha-
betical order. For each global variable, the Global Function Library Manager contains variable names, data types, and default
values. In the Libraries column, libraries are listed in alphabetical order.
