Hi,
I need to find the way to execute scripts from main script in current environment, but not use "." (dot)  before script name
Example

#!/usr/bin/ksh
.  ~/script1
.  ~/script2

Maybe use some flag in ksh, etc...

Thanks in advance

Why not just

~/script1
~/script2

Where's the problem? Do you have to give back environment variables to the main script? That's the only reason for the dot I could imagine.

Of course you have to "export" variables which must be known by the called scripts.

And finally, what's wrong with the dot? Why don't you want to use it?

It is interactive tool I wrote. Variables going back and forward from script to script but stay inside actual session. I need to encrypt scripts but encryption tool  doesn't like dot. In tcsh it is easier (source instead dot) but I don't want to re-write all.

So why not "export" the variables which must be made available to called scripts?  ksh does this automatically when invoked with the "-a" flag.

To make variables set in a called script available to the calling script there is no other way than using the dot or "source", if you don't want to use an external config file.

"bash" allows using "source" instead of the dot and is widely compatible with ksh. Could  bash be an option?

Another idea: Export a variable called SOURCE in the main script:

export SOURCE="command . "

and use $SOURCE instead of the dot, like:

$SOURCE ~/script1
