TurboIMAGE/XL Library Procedures
DBGET
NOTE A call to DBOPEN does not open individual data sets. Thus, a call to DBGET (or
DBFIND) that accesses a data set for the first time (or after the data set has
been closed), must open the data set as well as jumbo files and B-Tree index
files. This causes extra overhead not incurred by subsequent calls to the same
data set by DBFIND or DBGET.
