NOTE: errstr was renamed to errsym. Added errsym builtin function. The errsym(errnum | "E_STRING") builtin, , when given a valid integer errnum that corresponds to a calc error condition, will return an E_STRING string, AND when given a valid E_STRING string that is associated with a calc error condition, will return errnum integer that corresponds to a calc error condition. Supplying a non-integer numeric errnum code to error(), errno(), strerror(), or errsym() will result in an error.

NAME
|
|
errcount - return or set the internal error count
|
|
|
|
SYNOPSIS
|
|
errcount([num])
|
|
|
|
TYPES
|
|
num integer
|
|
|
|
return integer
|
|
|
|
DESCRIPTION
|
|
An internal variable keeps count of the number of functions
|
|
evaluating to an error value either internally or by a call to
|
|
error() or newerror().
|
|
|
|
The errcount() with no args returns the current error count. Calling
|
|
errcount(num) returns the current error count and resets it to num.
|
|
|
|
If the count exceeds the current value of errmax, execution is aborted
|
|
with a message displaying the errno for the error.
|
|
|
|
If an error value is assigned to a variable as in:
|
|
|
|
infty = 1/0;
|
|
|
|
then a function returning that variable does not contribute to
|
|
errcount.
|
|
|
|
EXAMPLE
|
|
; ## NOTE: Your output may vary:
|
|
|
|
; errmax(10)
|
|
0
|
|
; errcount()
|
|
0
|
|
; a = 1/0; b = 2 + ""; c = error(27); d = newerror("a");
|
|
; print errcount(), a, errcount(), errmax();
|
|
4 Error 10001 4 10
|
|
|
|
