When DLLCall is called with a return type of B (IEEE 8 bit floating point variable) nothing is returned to Citect. DLLCall does not support floating point returns from DLLCall in versions 3.x and 4.x.

Solution:

CIT has confirmed this to be a problem in Citect for Windows version to 4.20. This problem has been fixed in version 5.00.
