Which shell are you using? Really shouldn't make a difference since this is common for all the shells.
I tried doing it and it is succesful in displaying the variable MY_NAME.
Can you show me your steps with the output..?
Hi nua, i realised my mistake. My initial run.sh script was
I ran the script and after that did a echo $NAME at the command promot.Nothing was printed.
I rewrote the code
and ran again, JOE was printed. In the first case, echo $NAME yielded nothing because it was only executed after the run.sh was executed;hence whatever variables inherited could have been/probably lost.Since they are only valid for the lifetime of the run.sh script. In the second example, echo $NAME was done within the script.Therefore whatever variables inherited will still be valid.

variable
variable(n) Tcl Built-In Commands variable(n)
__________________________________________________________________________________________________________________________________________________NAME
variable - create and initialize a namespace variable
SYNOPSIS
variable ?name value...? name ?value?
_________________________________________________________________DESCRIPTION
This command is normally used within a namespace eval command to create one or more variables within a namespace. Each variable name is
initialized with value. The value for the last variable is optional.
If a variable name does not exist, it is created. In this case, if value is specified, it is assigned to the newly created variable. If
no value is specified, the new variable is left undefined. If the variable already exists, it is set to value if value is specified or
left unchanged if no value is given. Normally, name is unqualified (does not include the names of any containing namespaces), and the
variable is created in the current namespace. If name includes any namespace qualifiers, the variable is created in the specified names-
pace. If the variable is not defined, it will be visible to the namespace which command, but not to the info exists command.
If the variable command is executed inside a Tcl procedure, it creates local variables linked to the corresponding namespace variables (and
therefore these variables are listed by info locals.) In this way the variable command resembles the global command, although the global
command only links to variables in the global namespace. If any values are given, they are used to modify the values of the associated
namespace variables. If a namespace variable does not exist, it is created and optionally initialized.
A name argument cannot reference an element within an array. Instead, name should reference the entire array, and the initialization value
should be left off. After the variable has been declared, elements within the array can be set using ordinary set or array commands.
