FNAME

forms a full filename from its components

<LABEL> - Results label to hold the full filename
<AREA>  - Midas software branch (HOST, CFG, DAT, etc) or aux name if <OPT>=AUX
<NAME>  - Filename (MYFILE, DEMUX, etc.)
<EXT>   - Filename extension ("txt", "mm", etc.)
<OPT>   - Option name (SYS, UCL, DSP, etc.) or "AUX"

This command splices together a filename unique to the OS and option area
selected.  The root of an option tree can be found by entering empty strings
for <AREA>, <NAME> and <EXT>.

If <OPT> is set to AUX, <area> is assumed to be a data auxiliary, otherwise
it is assumed to be a subdirectory of the named option tree.  Since NeXtMidas
3.5.4, the WRITE AUX path is now fully resolved.

If the /PARSE switch is present, the command works in reverse with ONE
IMPORTANT DIFFERENCE -  The <AREA> arg will actually contain the path.  No
attempt is made to relate this to an area.  Given a fully specified filename
in <LABEL>, the components will be written into the results names specified in
the <AREA>, <NAME>, and <EXT> slots where:
  <AREA> - Is the file path
  <NAME> - Is the file root name (without extension)
  <EXT>  - Is the file extension

Examples:
 To find the ROOT directory of the SYS option tree:
    nM> FNAME sysDir AREA="" NAME="" EXT="" OPT=SYS

 To parse the filename in the results myfile into its path, name, and ext
    nM> FNAME/PARSE myfile itspath itsname itsextension

 To name a file in the users home directory:
    nM> FNAME myfile HOME mymacro mm AUX

 To name a file in the users write directory:
    nM> FNAME myfile WRITE log txt AUX
    Note: Since NeXtMidas 3.5.4, the path is fully resolved.
    nM> res myfile
    24S: MYFILE          = \midas\data1\usr\log.txt

 To name a file in aux=99 directory:
    nM> FNAME myfile 99 world prm AUX

 To open some java code from the macro language
    nM> FNAME mycode prim plot java sys
    nM> FILE open/t myfile mycode

 You can also reference a file in the software tree directly using the "nxm dot"
 package syntax:
    nM> FILE open/t myfile nxm.sys.prim.plot.java

Switches:
  /FNCASE= - Sets the FileName case-sensitivity (LowerCase,KeepCase,AutoCase)
             similar to the FNCASE= qualifier. This only applies when /PARSE is
             *not* used.                                 (Since NeXtMidas 3.3.1)
  /PARSE   - Parse the file given by <LABEL> into its path (<AREA>), root name
             and extension. FileName case-sensitivity can be set via the FNCASE=
             qualifier on the file name passed in.
