Setting PL/I Parser preferences

Use this page of the z Systems® LPEX Editor preferences to enable the 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 checkboxes. To disable margin lines, clear the checkbox. Changing these preferences updates every open instance of the editors.

Enable left margin line: Enables a vertical margin line at the column number indicated.
Enable right margin line: Enables a vertical margin line at the column number indicated.

For PL/I, in addition to the margin settings, which affect 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 by 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 compilation option [such as MARGINS (3, 75)] overrides the values that are set in this preference page.
