7526 DCT Reference
The validation transaction format accommodates 1-12 character file
names. The format is:
- V = validation transaction
- nn = field number
- RS = Record Separator, present if file name is more than one (1) character
- fff..ff = file name (1-12 characters)
- RS = Record Separator, present if file name is more than one (1) character
- v = validation type, present or absent
- ll = length of the field
ddd..dd = data to validate
In the case of a transaction requesting remote validation, the format of the
transaction record is as follows:
- Byte 1 = ASCII V
- Bytes 2-3 = decimal number (01-99) which indicates the nth
':' or ';' in the transaction program
- Byte 4 = File ID of validation file on the terminal controller (A -
Z, a-z)
- Byte 5 = Validation type (always 1 - positive validation)
- Bytes 6-7 = Length of data field to verify in decimal (01-99)
- Bytes 8-end = ASCII data that needs remote validation
