inputlevel - current input level
SYNOPSIS
inputlevel()
TYPES
return nonnegative integer
DESCRIPTION
This function returns the input level at which it is called.
When calc starts, it is at level zero. The level is increased
by 1 each time execution starts of a read file command or a call to
eval(S) for some expression S which evaluates to a string. It
decreases by 1 when a file being read reaches EOF or a string
being eval-ed reaches '\0', or earlier if a quit statement is
encountered at top calculation-level in the flle or string. It
decreases to zero if an abort statement is encountered at any
function-level in the file or string. If a quit or abort
statement is encountered at top calculation-level at top input-level,
calc is exited.
Zero input level is also called top input level; greater values
of inputlevel() indicate reading at greater depths.
