[CLOSED] Split Alpha Field to Individual Records?

I have a data field that appears to be A255 format, but it is holding multime records in the single field.

There appears to be a record delimiter of "", and a field delimiter of "".

Is it possible to create a new hold file that would split the A255 field into indivisual records?

Once I split them into individual records, I'm guessing I can use GETTOK to split the record into individual fields.

Thank you.

You can do that before you take it to a HOLD file. Use DEFINE fields to break the large field into individual fields.
FIELD2/An=GETTOK(FIELD1,len1,tno,'delim',olen,format); .... separate fieldname at delimiter
FIELD1: .... alphanumeric fieldname or 'literal' to be separated
len1: .... length of FIELD1
tno: .... divide at which delimiter instance (n=from left, -n=from right)
delim: .... separate at this character
olen: .... maximum length of the output value
FIELD2: .... string extracted from tno-1 to tno
format: 'An' .... specify the receiving format
format: fieldname .... specify a fieldname having the required format

Breaking your 1 field into multiple records will require the use of the McGyver technique (look it up) which allows you to "multiply" a single record into many based on some condition of your choice.

i can't tell what the record delimiter is, in your post above,
but another approach might be to write an MFD that declares this file as a DFIX with a delimiter set to be whatever that record character is.
then read and write out as records
then repeat using another master with another delimiter to separate the records into fields.
Lather ,rinse, repeat.
I prefer POSIT and SUBSTR functions to POSIT, (but i'm just stuck in my ways.)

The delimiter appears to be the ascii equivilent of decimal 192. I tried copy/pasting it from the data and it does not appear to have worked.

Old trick - may still work:
Hold down the ALT key then press 192 on the numeric keypad. Used to insert the ascii 192 character.

Building on the suggestion of susannah, if the field is truly A255 (not A255V) and all the data elements are of a fixed length within the field, you can just write another Master File describing each of the individual elements as A12, A24 A64 etc.. You can then issue the USE FILENAME AS NewMaster to access the individual elements within the large field.
The total length must be the same (A255) and you must allow for the delimiters (usually A1).
