FILENUM Library
This section is currently being reworked. We apologize for the inconvenience. If you need immediate assistance, please contact Tibbo Support.
The FILENUM library automates file number assignment. The fd. object supports up to fd.maxopenedfiles opened files. Using the FILENUM library, your code can get an unused file number, work with the file "on" this number, then release the file number into a pool of free file numbers.
