---------------------------------- Example ---------------------------------
setmode(1) && switch into 40x25 alphanumeric
? getmode()
* prints 1
setmode(43) && switch into 43 line EGA
? getmode()
* prints 3 - the real mode in use when in 43 line mode
tempvar = getmode()
setmode(43)
** do something **
setmode(tempvar)
Note: When using 43 or 50 line mode, getmode returns 3 because that
is the real video mode being used. To check for 43 or 50 line
mode you can use the maxrow() function.
