linσ i≤ structureΣ a≤ follows:
l[o][command]
where:
l is the single character used to invoke the command
note that it may be upper- or lower-case
o is an opening option, which is one of:
:nn -- go to Menu nn
! -- have VMENU wait when the command is finished
command is an optional ZCPR3 command; note that if
the option is ":nn", then a command here makes no
sense
The VMENU commands are:
Command Function
:nn Goto Menu nn, where the first menu is Menu 1
! Wait after command line is executed before
processing the menu
"Prompt" Prompt the user for input and accept it
The VMENU variables are:
