Adding GUI functionality to TCL script

hello thanks for this thread is very usefull.

my problem is:

to execute this first.tcl file i put quartus_sh -t first.tcl in the tcl windows and execute it well.

but when i want to introduce another actions from others packages (like quartus_pgm -m JTAG -op;DPD.sof) in the proc yes (for example) the tcl command says:

invalid command name "quartus_pgm"

while executing

"unknown_original quartus_pgm -m JTAG -op"

how i can use diferent packages (like quartus_stp and quartus_sh) in a single tcl file?

it is posible?

thanks

i hope you understand my cuestion.

bye.
