Update the Field Data

To update the data of a specific field:

• Specify TSSHEAD of TCPLV5L1.
• Specify a TSSCLASS name of FLDXTR.
• Specify the segment name in TSSPPGM.
• Specify the field name in the TSSRNAME field.
• Specify a four‑byte word to contain the length of the field, and then specify the data to be stored in the TSSRTN field. (The four‑byte length goes in front of the data.)
• The TSSLRTN field should be set to a value of at least the length of the FDT field to be extracted.

CA Top Secret updates the field data by replacing the old data with the supplied data. Data extracted with FLDXTR is taken from the ACEE at the time it was initialized. If FLDUPD has taken place after initialization, FLDXTR will not reflect these changes.
