# EM, HD, PM Parameters for Field/Variable

( |  | `EM=`value `EMU=`value |  | [`HD=`'text'] [`PM=`value])

For an explanation of the symbols used in the syntax diagram, see Syntax Symbols.

The `emhdpm` option is used to define additional parameters to be in effect for a field/variable.

Note
If for a database field you specify neither an edit mask (`EM=` or `EMU=`) nor a header (`HD=`), the default edit mask and default header as defined in the data definition module (DDM) will be used. However, if you specify one of the two, the other's default from the DDM will not be used.

## Syntax Description

Syntax Element | Description
--- | ---
`EM=value` | Edit Mask: The `EM` parameter may be used to define an edit mask used when the field is displayed with an I/O statement. For further information, see the session parameter `EM` in the Parameter Reference.
`EMU=value` | Unicode Edit Mask: The `EMU` parameter may be used to define a Unicode edit mask used when the field is displayed with an I/O statement. For further information, see the session parameter `EMU` in the Parameter Reference.
`HD='text'` | Header Definition: The `HD` parameter may be used to define the header to be used as the default header for the field. For further information, see the session parameter `HD` in the Parameter Reference.
`PM=value` | Print Mode: The `PM` parameter may be used to set the print mode, which indicates how fields are to be output. For further information, see the session parameter `PM` in the Parameter Reference.
