DIM (631) would define the memory area for the table of records.
Not able to post image. DIM has four values
N = table number = #0
LR = Length of record = #5
NR = Number of records = #A (10 decimal)
TB = First Table word = D100 (arbitrary memory location)
Database would be in D100 - D150. This only creates the memory area for the database.
You will need to use SETR (635), GETR (636), SRCH(181) to manipulate the data.
Hope this helps,
