To disable truncation of characters, set maximum line length to -1. For more information, see Setting language-specific maximum line length.
zopeneditor.rexx.maximumLineLength
Provides a maximum line length for the REXX editor. This setting will allow the editor to truncate all text after the provided column number while saving a document. To disable truncation of characters, set maximum line length to -1. For more information, see Setting language-specific maximum line length.

zopeneditor.userbuild.userSettings
Settings for IBM User Build. See the IBM Documentation for details.
zopeneditor.welcomePage.show
Show the welcome page on VS Code startup.
zopeneditor.zapp.useDefaultOnlineZappSchema
Z Open Editor comes with the built-in ZAPP JSON schema. It can be used for YAML files using Red Hat's YAML VS Code extension, and for JSON files with the built-in editor. If you encounter issues locating this built-in schema on deployments like Eclipse Che, such as being unable to see syntax errors with the Red Hat YAML extension, enable this option to load the schema from the internet.
zopeneditor.zapp.customZappSchemaLocation
When you work offline but have to provide a path to the ZAPP schema yourself, such as in a custom Che deployment, specify a valid HTTP or file URL to the location of the ZAPP JSON schema. If specified, the Use Default Online Zapp Schema option will be ignored.
zopeneditor.zcodeformat.useDefaultOnlineZCodeFormatSchema
Z Open Editor comes with the built-in zCodeFormat JSON schema. It can be used for YAML files using Red Hat's YAML VS Code extension, and for JSON files with the built-in editor. If you encounter issues locating this built-in schema on deployments like Eclipse Che, such as being unable to see syntax errors with the Red Hat YAML extension, enable this option to load the schema from the internet.
zopeneditor.zcodeformat.customZCodeFormatSchemaLocation
When you work offline but have to provide a path to the zCodeFormat schema yourself, such as in a custom Che deployment, specify a valid HTTP or file URL to the location of the zCodeFormat JSON schema. If specified, the Use Default Online zCodeFormat Schema option will be ignored.
zopeneditor.zowe
The zopeneditor.zowe setting can be used at a user or workspace level. Typically every user specifies these in their user settings using their personal profile names. If defined in workspace settings then it is assumed that all users of this workspace have defined the same standardized profile names on their systems. If set at both levels, the user and workspace level, the workspace level will override the user level.
Use "zopeneditor.zowe": {"defaultCliProfile": "profile"} to specify the profile you want to use for IBM Z Open Editor operations. If this is not defined, IBM Z Open Editor follows the precedence rules described in Setting up and using RSE profiles in IBM Z Open Editor to identify which CLI profile to use.
Use "zopeneditor.zowe": {"defaultRseConversionMappingsFile": "<absolute pathname>"} to specify the path to a valid RSE API mappings file or ZAPP file that contains RSE API mappings. These mappings will be used for Zowe Explorer MVS file content read/write operations for RSE API profiles. Note, that property groups for remote include file resolution and user build will not use this setting, but look for a workspace-local ZAPP file or if not found, a mappings file in the user's .zowe/profiles/rse directory.
zowe.files.temporaryDownloadsFolder.cleanup
The zowe.files.temporaryDownloadsFolder.cleanup setting is adopted from Zowe Explorer settings to support the use of multiple VS Code windows showing the same files opened via Zowe Explorer so you can see different parts of the same program on two different screens. Note that disabling the cleanup will result in files downloaded from z/OS not being removed when the editor is closed or restarted, so when you open a file via Zowe Explorer you may be viewing an outdated local version. Use the right-click "Pull from Mainframe" command to ensure you are working with the latest files.
