Why UNITS does not show all the files opened via HISTO/FILE ?


Since we use C I/O to access HBOOK files on Unix platforms the UNITS command does not return anymore the connected HBOOK files. The problem is that UNITS works by looping over all luns from 1 to 100 and doing an INQUIRE. The Fortran I/O runtime stores the filenames and returns them to INQUIRE. However, the C runtime does not store the filenames used to open the files and therefore we can not implement this feature (in C we only can find out which file descriptors are in use, not the names used to open these file descriptors).

To see which HBOOK files are connected do 'LD //'.

Since version 2.09/18 of PAW the UNITS command is again able to display the list of HBOOK files.
