I have uploaded a new VBI.ZIP with some changes that intend
to solve issues.

Not elegant but hopefully sufficient for people to be able to figure
it out.

Example:

$ type vms_vbisam.com

$ cc/float=ieee/incl=disk1:[net.vbisam-2_0_1] vms_vbisam
$! cc/float=ieee/incl=disk1:[net.vbisam-2_1_1]/define="API21" vms_vbisam
$ exit
