CHD. Command
Change current Directory and Drive
Intention
Change the "current directory". This command is somehow like CHDIR in old DOS times, but it will also change the current Drive. Usage is simple:
' Please use folders that are valid on your system
CHD.F:\00_S-Files\00_Desktop
DBP.?curdir\
CHD.?ws\
DBP.?curdir\
ENR.
Will result in something like this.
As you can see, we can switch the drive and the current directory in one strike.
If you only want to switch the current drive you can do it like that:
CHD.|C
The second parameter can be as long as it is, only the first letter on the left side will be taken, it should be a valid drive letter. For example:
VAR.$$FIL=F:\00_S-Files\00_Desktop
CHD.|$$FIL
is completely valid.
Note: CHD. will execute the command internally and then place the current directory on TOS. If CHD. will run into an error, you will find the unchanged current directory on the TOS.
