Specifies what Host Integrator should do if you attempt to insert a character in a 3270 terminal session. The values are:
|First Null (default)||Make room for the character being inserted by moving all characters to the right of the insertion point one character to the right until a null is encountered. The null is replaced by a character and all subsequent characters are unchanged. If no null is found, the insertion fails.|
|First Null Or Trailing Space||Uses the same logic as First Null, except that a trailing space can be used if no null is found.|
|First Null Or Trailing Character||Replaces the last character in the insert arena on an insert if neither a null nor a trailing space is found.|
The logic Host Integrator applies can be over a single field, multiple local fields, or all unprotected fields.
