Passing variable from called script to the caller script
Hi all,

Warm regards!

I am in a difficult situation here. I have been trying to create a shell script which calls another shell script inside. Here is a simplified version of the same.

Calling Script.

Code:
#!/bin/ksh

# want to run as a different process
/path_to_called_script/called_script.ksh 10 20

#some other operations

called script
Code:
#!/bin/ksh

sqlplus -s ${connection} <<EOF

sample_procedure($1,$2);
exit;
EOF

problem is $1 and $2 is coming as empty . it contains nothing. What's the correct procedure to pass variable into sqlplus from shell script? please help.


let me know in case additional info is needed.

Shell in use -ksh

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
	   able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
	   performed.
