Working with exec in ksh

hi
i have a script in this script i need to invoke another one that should set some environment vars

i tried using the exec command from my script but the program is exiting after the second script (that was executed with exec) how can i set the env vars ( or invoke the second script) without exiting

the code looks like the following:
####my_script

#!/bin/ksh
echo "before ld_path = $LD_LIBRARY_PATH"

exec ~/scond_script

echo "after ld_path = $LD_LIBRARY_PATH"

exit


### second_script
#!/bin/ksh
export LD_LIBRARY_PATH_64=blabla



10x in advance

exec will run the command in the same process as the calling process, and thus an exit will terminate that process.

What you wish to do is to source the seconf scritp using the . command (yes, that is a dot):

plese note the space after the dot.

i am using now the ssource command in ksh (". ")
but now i have a new problem my second script is tcsh
and have its syntax and i get syntax error while executing
what do i need to do

I thought you said the second script was ksh (as in the shebang line at the start stating /bin/ksh).
I am not sure what the rules of sharing environment variables between shells are. I suspect you may need to source the file one more, in the tcsh script to re-setup the variables.

i will try
