This feature does not allow your program to add data characters in place
of fill characters removed from the string. This feature changes the
position of the data.
When header and trailing characters are removed from a data string, only
the balance is counted as data in the string. Trailing characters are not
removed until the data string exceeds the set string length. The first
characters of the string are counted by the module as header characters
and can be removed regardless of the number of characters in the string.
1. Set the number of header characters (three) and trailing characters
(four) to be removed be setting IW4(00-03) and IW4(04-07) to 3 hex
and 4 hex, respectively. Use the procedure in section titled
“Demonstrating End-of-String Delimiter”, P. 3-9. Retain previous
initialization data.
Display The initialization word file is displayed in hex and binary,
respectively, as follows:
