// This function is a development of Jeff's orginal work for ver 7.100
// it converts variables or symbols to HAL signal names (if present)
// It is called from the GetElementPropertiesForStatusBar function in edit.c
// it checks to see if the VarsNameParam is a symbol, if it is, converts it to a variable name
// if Variable is B or W then exports that it is a memory variable
//also checks to see if in the range of max number of word variables loaded by realtime
// if not I, Q, QW, or IW then returns an error message
// then checks for what the pinname would be if it is a I, Q, IW or QW variable
// (these are the only variables that can connect to the outside world)
// if I or Q checks to see it is really QW or QI then checks
// if in the range of number of HAL pins loaded by realtime module
// then checks to see if a signal is connected to that pin
// if there is a signal returns that name with an arrow to show if the signal is coming in or going out
// if there is no signal connected returns that fact
// anything else should return an error
