Rational Developer for System z

PL/I Parser

Use this page of the System z® LPEX Editor preferences to enable the System z LPEX Editor to display margin lines for quickly and easily checking column alignments in a PL/I file.

To enable margin lines, click one of the following check boxes. To disable margin lines, clear the check box. By default, these margin lines are disabled.
Enable left margin line
Enables a vertical margin line at the column number indicated.
Enable right margin line
Enables a vertical margin at the column number indicated.
For PL/I, in addition to the margin settings, which affects the parsing of the text, there is also the fields setting, which divides the edit area into different edit fields, preventing text from moving from one field to another when characters are inserted or deleted. Although they are different settings, margins and fields are closely related. Whenever you change the margins in PL/I using this preference, the fields are adjusted as well. For example, if the right margin value in the preference is specified as 75 and the fields option is set to "1 73 81," then the fields setting is adjusted to "1 75 81".
Note: The MARGINS compile-time option [such as MARGINS (3, 75)] overrides the values set in this preference page.
