Both parameters of O-String mentioned above are numbers. But both parameters can be
specified as strings. If N is a string, it becomes a position and the meaning of O-String will be
"Output from position P to position N".
If P is defined as:
"ab...ik"
a, b, I, and k can be any character, the position will be evaluated as
-- Start from the first position of the original string and search character 'a'.
-- From the position next to 'a' in original data, search for 'b'.
-- ....
-- From the position next to 'i', search for k.
-- If above searches are all found, the result of the parameter will be the position where 'k' is
located.
If N is a string, the position evaluation of N is the same as P except that the searching position
is starting from P+1.
For both P and N, if string is defined, a value can be added to or subtracted from the position.
That following O-Strings:
"ab...ik"+M,
and
"ab...ik"-M,
are meaningful. M is an integer number.
Example:
Suppose the following is a message to be modified:
%B012345678901234^ABEL/STEVE L MGR ^90010129999999?
In this message:
"%" is start sentinel.
"012345678901234" is account number.
"^" is a separator
6. "ABEL" is surname.
"/" is a separator.
"STEVE" is first name.
"L" is initial.
"MGR" is title
"^" is a separator.
"9001" is expiration date.
"?" is end sentinel.
The output sequence desired is:
Surname, First Name [CR] Account Number [CR] Expiration Date [CR]
The formula input will be:
IN_ID,0,O-STR,"^"+1,"/"-1,",",O-STR,"/"+1,"<SP>"-1,"<CR>",O-STR,3,"^"-1,"<CR>",O-STR
,"^^"+1,4,"<CR>",Enter
Here <SP> is Space character and <CR> is Carriage Return character.
