FILES command to find the name of the shape (.shp ) file
that is located in the dat area of SYS.
nM> files ext=shp aux=dat Auxiliary [DAT] = /home/student/nxmlatest/nxm/sys/dat/ (1 files) world.shp STATUS command to find out the size (number of bytes) of the
shape file in the dat area of SYS. (Data displayed is from NeXtMidas 3.8+)

STATUS with the /d switch to list the header
and data in airports.csv . But, this time, give it the
HEADERROWS=1 qualifier, and see what happens.

temp_xxx_file.tmp , temp_yyy_file.tmp ,
temp_xyx_file.tmp , and temp_zzy_file.tmp . Then use
the FILES command to find all files starting with temp_,
with a y somewhere after the temp_ and ending with _file.
Use the FILES/E command to erase all of the files you created.
