NAME calclevel - current calculation levelSYNOPSIS calclevel()TYPES return nonnegative integerDESCRIPTION This function returns the calculation level at which it is called. When a command is being read from a terminal or from a file, calc is at calculation level zero. The level is increased by 1 each time calculation starts of a user-defined function or of eval(S) for some expression S which evaluates to a string. It decreases to zero if an error occurs or a quit or abort statement is executed. Otherwise, it decreases by 1 when the calculation is completed. Except when an error occurs or abort is executed, the input level is not affected by changes in the calculation level. Zero calculation level is also called top calculation level; greater values of calclevel() indicate calculation is occurring at greater depths.EXAMPLE n/aLIMITS noneLINK LIBRARY noneSEE ALSO eval, read, quit, abort, inputlevel## Copyright (C) 1999 Landon Curt Noll#### Calc is open software; you can redistribute it and/or modify it under## the terms of the version 2.1 of the GNU Lesser General Public License## as published by the Free Software Foundation.#### Calc is distributed in the hope that it will be useful, but WITHOUT## ANY WARRANTY; without even the implied warranty of MERCHANTABILITY## or FITNESS FOR A PARTICULAR PURPOSE.
