DyalogStartupSE

This parameter specifies one or more Session initialisation directories that contain APL code to be installed in ⎕SE. If this parameter is not specified, the default is a directory named StartupSession located in three standard locations.

Under Windows these might be:

1. C:\Program Files\Dyalog\Dyalog APL-64 19.0 Unicode
2. C:\Users\Pete\Documents\Dyalog APL Files
3. C:\Users\Pete\Documents\Dyalog APL-64 19.0 Unicode Files

The version-specific name is :

     Dyalog APL{bit} {version} {edition}

where:

• {bit} is "-64" if 64-bit version, otherwise nothing
• {version} is the main and secondary version numbers of dyalog.exe separated by ".".
• {edition} is "Unicode" for the Unicode Edition, otherwise nothing

The parameter is a string containing the list of directory names separated by ";" on Windows, ":" elsewhere.

If DyalogStartupSE begins with the specified separator, the default list is extended rather than replaced.

Note that the effective sequence of directories specified by this parameter is converted to a vector of character vectors and stored in ⎕SE.Dyalog.StartupSession.AllPaths.

If unset or extended (that is, starts with a : separator):

• the effective StartupSession directory in [DYALOG] is available as ⎕SE.Dyalog.StartupSession.Dyalog.
• the StartupSession directory in the version-agnostic directory is available as ⎕SE.Dyalog.StartupSession.VerAgno.
• the StartupSession directory in the version-specific directory is available as ⎕SE.Dyalog.StartupSession.VerSpec.
