It looks like you are calling various Perl scripts from from within shell. Basically, each Perl process has its own range of memory, and one process cannot access another processes memory structures (for obvious reasons) without using some form of IPC or persistence.

I would recommend in your case to use serialization and store the data in a file so the other process can easily access it. A quick search came across this:

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)
