7.34 Custom User Opcode (USRINTR and
USRCONT)
These opcodes are part of the open software extensions to the RVP900,
which allow custom opcodes to be defined for each major mode of
operation. Arguments may be passed into a custom opcode handler as an
XARG list. Likewise, an optional array of words returned from that
handler will appear after the command executes.

7.35 Load Melting Layer Specification (MLSPEC)
The RVP900 allows to get melting layer specific information from the
latest melting layer product created in IRIS. The information includes the
melting layer height and the uncertainties. The specifications of the
melting layer are set as a function of range, azimuth, and elevation based
on the information coming from the configuration of the task and either the
melting layer product parameters used in the latest melting product created
or the melting layer product default parameters.
The RVP900 can use spatially variable melting layer (ML) altitudes, which
may be preloaded for each interval of data processing (PROC). The ML
altitudes are referenced to the Mean Sea Level, and estimate the top of ML.
UserBits Four additional bits defined by the user to help subdivide
the opcode functions if desired.
CON If set, then the RVP900 IQ data acquisition thread proceeds
continuously while the opcode is executed. If clear, then
the IQ stream is interrupted prior to handling the call.
