Version Ref: 4.8
Description:
OPENDIR() allows you to do the equivalent of a DOS "DIR" or UNIX "ls" command. It returns the number of files in a filePro directory that meet the criteria.
Version 6.0.01
NEW command OPENDIR2 to handle long-named files and paths.
e.x.
N = OPENDIR2(mask, path, fmt_sz, ext_sz, nam_sz)
All arguments are optional.
Returns the number of files which match the parameters. If no parameters are given, a count of all filePro filenames is returned. If only a mask is specified, it is applied to the current filePro file. There are pre-defined masks for filePro files, but any mask may be used. Only one OPENDIR() or OPENDIR2() may be active at one time.
mask - the filter applied to the directory, same as OPENDIR()
path - the directory to use
fmt_sz - the total size to use to store the format (default 32)
ext_sz - the size used to store the extension (default 10)
nam_sz - the size used to store the filename (default 32)
Note: the numbers used to define the lengths change the size used by the system controlled "@DIRLIST" arrays.
