how can i pass my dynamic variable from command to script?
example:
/sys script run MYSCRIPT MYVARIABLE
(MYVARIABLE can be dynamic like user1 or user2 etc)
IMHO the only way is to use global variables

Thank you for your reply. I already read that before posting, but its not a neat solution. I wanted to pass simple variable like we do in bash.
Example:
/sys scr run Myscript username1
/sys scr run Myscript username2
and so on to query some customized info using same script to pull specific users info.
Y its so hard to add this simple task in the MT Scripting 
Create global variable with some value (username1)
:global variable username1
Use $variable in your script. When you need, simply change the value of specified variable:
:global variable username2
This way you will be able to run same script, by only changing one variable.
You can also use functions.
Ok I got it. Every time i have to change the global variable first, then run the script. two steps burden 
All of you, Thank you for your support and suggestions
