-- 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 starts 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:
