When text strings greater than 200 characters are collected, the following conventions for general observation class variables and SUPP-- datasets will be adhered to:

• The first 200 characters of text should be stored in the parent domain variable and each additional 200 characters of text should be stored in a record in the SUPP-- dataset.
  • When splitting a text string into several SUPP-- records, the text should be split between words to improve readability.
  • The value of the first QNAM representing text over 200 characters will be the original domain variable name without any numeric suffix. 
  • The values for subsequent QNAMs will be sequential variable names, formed by appending a 1-digit integer, beginning with 1, to the original domain variable name. In cases where the standard domain variable name is already 8 characters in length, applicants will replace the last character with a digit when creating values for QNAM.
    • e.g., For Other Action Taken in Adverse Events (AEACNOTH), values for QNAM for the SUPPAE records would have the values AEACNOT1, AEACNOT2, AEACNOT3, and so on.

• For variables where the response is "Yes" or "No", both "Y" and "N" will be populated for responses. This eliminates confusion regarding whether a blank response indicates "N" or is a missing value.
• Some variables are collected or derived in a manner that allows only 1 response (e.g., a single checkbox for "Yes"). In situations such as these, where it is unambiguous to populate only the response of interest, only 1 value will be populated ("Y" or "N") and the alternate value will be blank.
