No. The C-ISAM libraries are built into the sqlexec executable and are not part of the ESQL/C distribution. Further, even if you buy C-ISAM, it is difficult to access the files from ESQLC because you have two programs (your ESQL/C application and the Standard Engine sqlexec) are trying to access the same files (mostly), and any lock placed by one of those processes prevents the other form accessing the same record -- because they are two separate processes. If the two programs will never be accessing the same records at the same time, and if you blow away any security you have on the database, then you can access the C-ISAM files from an ESQL/C program, provided you by the C-ISAM product as well as the ESQL/C product. But it is highly unrecommended! Yours, Jonathan Leffler (johnl@obelix.informix.com) #include <disclaimer.h>
