Usage: EditVar var

-b Place cursor at the beginning of the input string.
-l len Allow no more than 'len' characters (1 to 255).
-m Masked input ('*' appears for each typed character).
-n Allow only numeric input (0-9).
-o Start in overtype mode.
-p prompt Prompt the user with 'prompt' (enclose in quotes if it has spaces).
-t n Assume Enter was pressed if nothing typed in 'n' seconds.
-u Force entered characters to uppercase.
