'SUBDIR' version 1.0.0 (1987). TRS-80 Model 1/3 Ldos 5.n system to create and service subdirectories. It's still in the testing stages and may not be bug-free. Use care.

For LDOS 5.n use SYSTEM (SVC)



The SUBDIR programs were created for use on the LDOS 5.1.x operating system.

The function of the programs is to create sub-directories similar to those in the MS-DOS operating system. This allows better control over program placement, etc.

MKDIR/CMD - Creates the subdirectory. Syntax: MKDIR filespec:d. Where filespec is the name of the sub-directory (no extension) and d is the drive you wish to assign it to.

CD/CMD - Change directory. Allows switching between different directories on one disk. Syntax: CD filespec:d. Where filespec is the name of the sub-directory and d is the drive. To return to the root (normal) directory, enter CD :d.

PWD/CMD - Shows the paths of the directories, like MS-DOS's PATH. It shows all logical drives and the current active directory on that drive. If using the root directory, it displays /.

RMDIR/CMD - Remove directory. Removes a subdirectory from the disk. You must type in the file password. To remove the sub-directory TEST from drive 1, type RMDIR TEST/DIR.EZTO:1. (EZTO is the system password for system files).

The program seems to work rather well. The sub-directory only takes up 4.5k of regular directory space, yet it has a full 45k of storage space for its own programs. This space is then depleted throughout the disk itself.
