Example of displaying data with a template
The first task in this tutorial is to view data that has been structured into fields, without using a template. This demonstrates some of the display issues that can occur when unformatted data is viewed. In the next task, you view the same data, with a template.
- From the File Manager Primary Option Menu, select option 1. View.
- In the Data set name field for the input data set, type
'FMN.V14R1M21.SFMNSAM1'. - In the Member field for the input data set, type
FMNCDATA. - In the Copybook/template usage field, select option 3. None.
- Press Enter.
Figure 1 shows what this data looks like without a template.

The first twenty records in this member contain non-displayable characters represented by periods and other characters. Without a template, these records cannot be easily viewed or edited.
- When you have finished examining the data, press the Exit function
key (F3) to return to the Edit (or View) Entry panel.
Now let's view the same data using a template generated from the COBOL copybook supplied in FMN.SFMNSAM1(FMNCCPY).
- In the Data set name field for the Copybook or Template,
type
'FMN.V14R1M21.SFMNSAM1'. - In the Member field for the Copybook or Template, type
FMNCCPY. - In the Copybook/template usage field, select option 1. Above.
- Press Enter.
For this example, we want to display the data in tabular format. If the Format field (at the top right of the panel) does not contain
TABL, then overtype the first letter of its current value withTand then press Enter.The sample data is now shown in TABL display format, arranged in columns.Figure 2.

File Manager has used the first record type defined in the copybook to display the data and the first set of records (REC-TYPE = 01) are now readable. Any fields defined in the second record type (REC-TYPE = 02) that match fields defined in the first type are also displayed.
