import var and function from ksh script to another ksh script

Ih all,
i have multiples ksh scripts for crontab's unix jobs
they all have same variables declarations and some similar functions

i would have a only single script file to declare my variables, like:

var1= "aaa"
var2= "bbb"
var3= "ccc"
...
function ab { ...}
function bc { ... }
function cd { ...}
...

and import this from all my others scripts
? is there any way to do except using export command ?

[sourcing a sh script . myscript or ./myscript work but not in ksh]

thx

Sourcing some code to establish variables and functions should work fine in ksh. I do it all the time.
. /path/to/included file
. is the name of the command. It must be followed by a space. Then comes the file to be sourced.

. thescript dont work in ksh, my script is on the same directory

but . ./thescript work for sourcing in same directory

thank you
