executing perl with arguments in tcl

I have a question on perl/Tcl script execution ....

right now i have both perl and Tcl script working individually standalone but i want to integrate the perl script in a Tcl script .... and the perl has the arguments to be passed along with command line execution and this argument is actually passed through the tcl ....

ex:

Tcl script = abcd.tcl
perl script = abcd.pl


script description

abcd.tcl


set variable [variablename]
puts.....
get.....
.....
...
...
puts" need to execute the perl script here along with the argument"

eval exec perl /nfs/iind/home/skrish1x/scripting/online/filecreate_an $variablename



it would be really great if any of you can give idea how to get it running .... as its not executing in the tcl script .... perl has fre print commands and also it mainly does file handeling functions ...

Tcl_AllowExceptions(3)					      Tcl Library Procedures					    Tcl_AllowExceptions(3)

__________________________________________________________________________________________________________________________________________________

NAME
Tcl_AllowExceptions - allow all exceptions in next script evaluation SYNOPSIS
#include <tcl.h> Tcl_AllowExceptions(interp) ARGUMENTS
Tcl_Interp *interp (in) Interpreter in which script will be evaluated. _________________________________________________________________ DESCRIPTION
If a script is evaluated at top-level (i.e. no other scripts are pending evaluation when the script is invoked), and if the script termi- nates with a completion code other than TCL_OK, TCL_ERROR or TCL_RETURN, then Tcl normally converts this into a TCL_ERROR return with an appropriate message. The particular script evaluation procedures of Tcl that act in the manner are Tcl_EvalObjEx, Tcl_EvalObjv, Tcl_Eval, Tcl_EvalEx, Tcl_GlobalEval, Tcl_GlobalEvalObj, Tcl_VarEval and Tcl_VarEvalVA. However, if Tcl_AllowExceptions is invoked immediately before calling one of those a procedures, then arbitrary completion codes are per- mitted from the script, and they are returned without modification. This is useful in cases where the caller can deal with exceptions such as TCL_BREAK or TCL_CONTINUE in a meaningful way. KEYWORDS
continue, break, exception, interpreter Tcl 7.4 Tcl_AllowExceptions(3)
