Using multiple variable in command-lin

I have a SFTP site with multiple folders that I need to download all of the *.pdf files into multiple folders on our network. All of local folders and remote folders listed in a text file which I read using the "for /F (tokens=*)" format in a batch file.

for /F "tokens=1, 2 delims=;" %%A in (STD-Folders.txt) do "C:\Program Files (x86)\WinSCP\WinSCP.com" /log="C:\WinSCP\SFTP\Logs\Log.txt" /ini=nul /command "open sftp://my-sftp-site:v!so9tpjszd9O9@sftp.us2.pool.com/ -hostkey=""ssh-rsa 2048 zeKC3/C87n3L12jSehP7r9B1LKHs3Vqo/PguPtVnUxQ=""" "cd /"%%B "lcd E:\Faxes\"%%A "get -delete *.pdf" "lcd E:\Faxes\Z-IDXFiles" "get -delete *.idx" "exit"

This works well but this method opens a session and exits on every iteration. Having 70 folders to download takes a lot of time. I would like to establish one session and then use "cd /remotefolder1" "lcd/ localfolder1" "get -delete *.pdf"
"cd /remotefolder2" "lcd/ localfolder2" "get -delete *.pdf"
"cd /remotefolder3" "lcd/ localfolder3" "get -delete *.pdf"
etc...where the remotefolder1 and localfolder1 are variables from a text file. I do not want to have 70 "cd/" "lcd/ " and "get -delete" statements. Just one that will loop and replace the variable and execute ... replace and execute until the end of the file is reached. Something similar to:

"C:\Program Files (x86)\WinSCP\WinSCP.com" /log="C:\WinSCP\SFTP\Logs\Log.txt" /ini=nul /command "open sftp://my-sftp-site:v!so9tpjszd9O9@sftp.us2.pool.com/ -hostkey=""ssh-rsa 2048 zeKC3/C87n3L12jSehP7r9B1LKHs3Vqo/PguPtVnUxQ="

Start Loop:
"cd /"%%remotefolder "lcd E:\Faxes\"%%localfolder "get -delete *.pdf"
"cd /"%%remotefolder "lcd E:\Faxes\"%%localfolder "get -delete *.pdf"
"cd /"%%remotefolder "lcd E:\Faxes\"%%localfolder "get -delete *.pdf"
End Loop:

Until the end-of-file then "exit".

So make you for loop append a command to a (temporary) WinSCP script file, instead of running WinSCP.
And run WinSCP with the script file only after the for loop.

Can you give me an example of what you are suggesting?

Roughly something like this (untested):

I'll give this a go! Thanks
