Program Settings → Special Files

This options defines the editor to be used when calling Edit function (e.g. Edit Rexx Script). If you set this field to the string <DEFAULT>, Notepad.exe (Windows) or the default editor (macOS) will be used.

This field specifies an external ftp client to be used when a host directory entry is configured to use the external ftp-client rather than the built-in ftp window. It is intended to be a fully qualified path to an executable, e.g. C:\Program Files\FileZilla FTP Client\filezilla.exe or /Applications/FileZilla/Contents/macOS/filezilla. This executable will then be invoked with a host specific parameter which can be defined in the FTP tab of each host directory entry.

Shell defines a shell to be used, when calling the Command Shell function in the View menu. This shell is also called with the /C parameter if you issue a ZocShell command from within a ZOC REXX script.
 
Note: If you set this field to <DEFAULT> ZOC will use CMD.EXE for Windows and /bin/sh for macOS.

This file is a file in which ZOC logs connections and file transfers (C+/C- in the log means connect/disconnect, DL means download, UL means upload).

The filename can contain placeholders like Calls^2^3.log for date/time (see placeholder codes in the appendix).

If no path is specified, the call log is stored in the log directory. If the field is empty, no calls log is written.

This field defines the name of the file, into which the File Menu→Save-Screen function will save the contents of the terminal window.

The REXX script selected here will be called, when ZOC is started, when it terminates and when another communication method (connection type) is activated. You will find the technical details inside the sample file ZOCEVENT.ZRX and in ZOCEVENT.TXT in the script folder.

Here you can select which REXX script is called before a file transfer begins and after a file transfer was completed. The REXX script can modify the file name before the file is actually written to disk.

This can be used if you want to implement a complex file storage scheme (e.g. if ZIP files are uploaded from different directories than other files or if you have special download directories for ZIP files, mail files and pictures) or if you want to automatically run an file compression utility before uploading certain files (and upload the compressed file instead). Additionally you could automatically unpack all downloaded ZIP files or decrypt incoming PGP files etc.

You will find the technical details inside the sample file ZOCXFER.ZRX and ZOCXFER.TXT in the script directory.

By default ZOC uses an internal REXX processor (Regina REXX) which is provided together with the ZOC program.

However, if you prefer a different REXX language implementation, or if you are already using a different REXX product that is compatible to the IBM's original REXX API, you can specify one or more DLL names here (multiple entries are separated by a vertical bar).

The following is a list of entries to be made to use the most common commercial and freeware implementations:
