Example

See additional examples

ADirectory, ResListDirectory are strings
DirectoryToList is string
DirectoryToList = "C:\MyDocuments"
// Windows Mobile: DirectoryToList = "\MyDocuments"

// List all the directories present in DirectoryToList.
ResListDirectory = fListDirectory(DirectoryToList)
// For each directory found
FOR EACH STRING ADirectory OF ResListDirectory SEPARATED BY CR
// Add the directory into TABLE_DirTable
TableAdd(TABLE_DirTable, ADirectory)
END

DirectoryToList = "C:\MyDocuments"
// Windows Mobile: DirectoryToList = "\MyDocuments"

// List the directories present in DirectoryToList.
// The DirectoryAttribute procedure returns the number of read-only directories.
ResListDirectory = fListDirectory(DirectoryToList, "DirectoryAttribute")
