NNNN
Primitive descriptor(s) and data unit(s) field length
supported, in bytes (270 bytes is returned)
MM
Number of Data Acquisition Blocks supported by the NIM
(For Primitives 50, 51, and 52, 32 is returned.)
EE
Number of Data Acquisition Records supported by the NIM
(For Primitives 55, 56, and 57, 32 is returned.)
FF
Number of Data Type Definitions supported in each defined
record in the NIM (For Primitives 55, 56, and 57, 32 is
returned.)
GG

00
No floating point support
01
IBM Excess 64 format support
02
IEEE Standard 754 format support
03
Both IBM and IEEE format support
BB
16 byte Primitive support bit mask for the NIM. The MSB bit
represents Primitive 0. Primitive values increment by 1 for
each bit position. A one in a bit position indicates that the
corresponding Primitive is supported. For example, if bit 3 is
set to 1, then Primitive 02 is supported.
