Assigning multiple values to a variable
Hi Guru`s,
I have to write a prog. which will traverse through diff. directories and then extract some data from files. I have written it and its working fine.
But I have tested it in 1 folder.
There are many folders and I need to loop through each of them. I am not sure abt the syntax/method of assigning multiple values to a variable and then using those values in the loop.
Eg.
folders like > cd /test/e101
cd /test/e102
cd /test/e103
I would like to define a variable say
var1 = e101,e102,e103
and then use it in loop like
cd /test/echo $var1
cd /test/echo $var1...
Please advise

for
for(n) Tcl Built-In Commands for(n)
__________________________________________________________________________________________________________________________________________________
NAME
for - ``For'' loop
SYNOPSIS
for start test next body
_________________________________________________________________
DESCRIPTION
For is a looping command, similar in structure to the C for statement. The start, next, and body arguments must be Tcl command strings,
and test is an expression string. The for command first invokes the Tcl interpreter to execute start. Then it repeatedly evaluates test
as an expression; if the result is non-zero it invokes the Tcl interpreter on body, then invokes the Tcl interpreter on next, then repeats
the loop. The command terminates when test evaluates to 0. If a continue command is invoked within body then any remaining commands in
the current execution of body are skipped; processing continues by invoking the Tcl interpreter on next, then evaluating test, and so on.
If a break command is invoked within body or next, then the for command will return immediately. The operation of break and continue are
similar to the corresponding statements in C. For returns an empty string.
Note: test should almost always be enclosed in braces. If not, variable substitutions will be made before the for command starts execut-
ing, which means that variable changes made by the loop body will not be considered in the expression. This is likely to result in an
infinite loop. If test is enclosed in braces, variable substitutions are delayed until the expression is evaluated (before each loop iter-
ation), so changes in the variables will be visible. For an example, try the following script with and without the braces around $x<10:
for {set x 0} {$x<10} {incr x} {
puts "x is $x"
}
