When performing WRITE or REWRITE operations on line sequential or line advancing files, the
INSERTNULL option determines whether to insert NULL (x"00") characters before non-printable characters. The option also determines whether to strip out those NULL characters during READ operations.
Syntax:
INSERTNULL
=
{
ON
}
{
OFF
}
Parameters:
- ON
- Insert NULL characters before non-printable characters. Strip out NULL characters during READ operations.
- OFF
- Do not insert NULL characters before non-printable characters. Do not strip out NULL characters during READ operations.
Comments:
INSERTNULL takes precedence over the N run-time switch.
If you do not set INSERTNULL, the setting of the N run-time switch determines whether or not NULL characters are inserted before non-printable characters.
