You can specify the number of lines to increment. Alternatively, click on the Eclipse toolbar. To remove the JCL line numbers from source code, right-click the source code and click Unnumber Alternatively, click on the Eclipse toolbar.
Shows the structure of the program you are editing which is useful for navigating large programs. Double-click on a statement to reposition the cursor to the respective line of code. You can also right-click an item in the outline and click Find References to display matches in the Search tab.
You can hover over items in the outline to display a pop-up containing the item's parameters. Similar to outline view, but displays the structure for all included JCL files. This shows a pop-up containing the structure of the code similar to the outline view. When you type while quick outline view is displayed you filter the list of displayed elements for easier navigation.
By default, trailing whitespace after column 80 is removed when you save a JCL file. You can remove all trailing whitespace when you save your JCL file. In the Remove trailing whitespace group, click your preference. To disable this feature, uncheck Remove trailing whitespace on save. Click the Show Whitespace Characters button on the toolbar to toggle between showing and hiding whitespace characters in the editor.
Whitespace characters include spaces, carriage returns, and end-of-line markers. Showing or hiding whitespace characters affects any JCL editor window you view. The code you type is parsed continuously to identify errors. The errors are underlined with red squiggly lines, and warnings are underlined with yellow squiggly lines.
You can hover over an error to see information about the error in an error message tool tip. Eclipse visualizes these tags in the Task tab. Double-clicking on the line in the Task tab takes you to the highlighted line in the editor.
Rows in the Task tab that are tagged TODO are high priority tasks and are highlighted with an exclamation point. You can add, remove or edit tags, specifying their priority as high, normal or low.

In the log display, this reserved run number will not be displayed. Natural source lines must be preceded by the activation escape character of the job see Symbol Escape Characters in the section Symbol Table and Symbol Maintenance.
The activation escape character at the beginning of a line distinguishes the line as a Natural statement from the JCL. This means you do not need to learn any special control statements. All Natural statements used in dynamic JCL must be coded in structured mode. Variables are user-defined and can be used in any part of the JCL, including the file name and control card. Variables are distinguished in the JCL by preceding them with an escape character: the activation escape character denotes variables to be substituted at activation time; the submit escape character denotes variables to be substituted at job submission time see Symbol Escape Characters in the section Symbol Table and Symbol Maintenance.
Note: These escape characters can be changed by the system administrator. However, this should only be done if absolutely necessary, for example for countries with a different alphabet. It is not advisable to use escape characters which have a defined meaning in a particular operating system or which are already defined as escape characters, e.
A local variable defined in this Natural program, which can be computed in your program L The variables used in the JCL are assumed to have the following current values:. When the job is activated, Entire Operations substitutes the variables with their current values. The following JCL is generated as a result:. The symbol is taken from where it is found first in the symbol search path. If it is not specified, the variable will be filled with the contents of a symbol with the same name.
To convert value to a numeric field, use the Natural VAL system function. With this syntax, an instance of a multiple value symbol can be obtained. The variable must be defined as a local array with a sufficient array size. The symbol will be set in the active symbol table which belongs to the active job. If it is not specified, the symbol will be filled with the contents of a local variable with the same name. The symbol will be set in the master symbol table which belongs to the active job.
The value may contain symbols itself. Refer to the examples in the following section. This is the only location which is currently allowed for text objects. If the text object cannot be read, the JCL generation will be aborted with an error message. This is limited by the line size.
Parameter values may contain blanks.
