Problem:

Although compiler directives can usually be specified in the file $COBDIR/etc/cobopt, in some circumstances, directives specified in that file might not take effect.

Resolution:

The explanation is that, when operating in 64-bit mode, a person must modify the file:

$COBDIR/etc/cobopt64

instead of the file:

$COBDIR/etc/cobopt

To solve the problem, first verify the operative bit-mode using the “cobmode” command, then make modifications to the corresponding “cobopt” file.
