# HI - Help Character

This Natural profile parameter defines the character which is to be used to invoke a field-specific helproutine or a map helproutine (if defined for a given map).

Possible settings | any special character | The character which is to be used to invoke a field-specific helproutine or a map helproutine. Note The character specified with the `HI` parameter must not be the same as the one specified with the `CF` (control character for mainframe terminal commands) parameter. In addition, we recommend that this character is not the same as the one specified with the `DC` (decimal character), `IA` (input assign character) or `ID` (input delimiter character) parameter.
blank | Notes: Numeric fields which have a helproutine assigned are internally translated to alphanumeric format so as to make it possible for the user to enter a question mark into the field to invoke the helproutine. To prevent this internal translation (that is, if you wish to make sure that alphabetical characters cannot be entered into a numeric field) you can set the profile parameter `HI` to blank. When `HI=' '` is set, a help key must be defined in the Natural application, using the `SETKEY` statement correspondingly; otherwise it is not possible to invoke a helproutine for any field.
Default setting | `?` | Question mark.
Dynamic specification | yes |
Specification within session | no |
Application programming interface | `USR0350N` | See SYSEXT - Natural Application Programming Interfaces in the Utilities documentation.
