-- 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:
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 a Space character and <CR> is a Carriage Return character.
