1. Introduction

This paper is a partial result from the accumulated experience and a research in the

field of improving the psychological environment for work on PCs.

It is a good practice for PCs to sort the files in a directory/folder by the date and

the hour in cases when the directory/folder is long enough and the number of files is

tremendous. Moreover the situation is additionally complicated by any mutually-con-

tradictory requirements (small RAM and intensive processing for example). Still it is

not possible to produce chronological references of the files if they are not sorted in

advance (the reason for this lies in the cluster principle of the file updates). The usage

of popular accessories like PC Tools and the File Managers either leads to intensive

charging the disk heads (the Update option of the DOS File Manager for a directory

of 381 files for PC XT is processed for 45 minutes) or the accessories themselves are

of significant dimensions (PC Tools Deluxe R4.21 is 170 996 B long).

It is possible to produce such references bypassing the popular accessories. The

approach for this can be realised in two ways: manual and program. The manual

solution is based on the usage of some text editor and a sorting between. The program

solution justs automatizes the manual solution.

The Internet (the global village) epoch resides on the PC Windows working

environment. This leads to the peculiar significance of the ShutDown option which

allows not only closing sessions with the successive turning off but also rebooting the

environment or changing the environment itself. The extension of this philosophy in a

downgrade manner brings to life the ShutDown-under-DOS monitor for older models

of PCs which can operate only under DOS or if there is a temporal abstination from

Windows. On the other hand such monitors seem to be the best illustration for appli-

cation of the program chronological file sorting.

The present paper introduces a program realization of the chronological file

sorting references by the xSList accessory (“x” may be equal to “D” or “F” which
