[udf-dlm-develop] Some questions

[Harald F. <hf...@ap...>]

Hi everybody,

first of all I want to wish everybody a happy and hopefully successful new year.
Now I have a few questions about the UDF-IDL DLM-interface.

1. Our WIC UDF contains the 256x256 image and several more single entries like 
the start_time, high_voltage etc. The command udf_read returns all these single 
numbers as 256-element arrays. Why? Is there a way around? I can certainly deal 
with the fact that I only consider element[0] as valid, but I consider this  
unnecessary additional effort.

2. Is it possible to get the number of records in a UDF file? Ed's example reads 
all records until the end of the file, but maybe there is a faster way?

3. The udf_read procedure returns the complete structure of the record. Is it 
possible to read only one particular variable, something like

d=udf_read(fh,variable='WIC_MCP_VOLTAGE_MONITOR')

This much of questions for now.
Harald
