NAME
|
|
errmax - return or set maximum error-count before execution stops
|
|
|
|
SYNOPSIS
|
|
errmax([num])
|
|
|
|
TYPES
|
|
num integer
|
|
|
|
return integer
|
|
|
|
DESCRIPTION
|
|
Without an argument, errmax() returns the current value of an
|
|
internal variable errmax. Calling errmax(num) returns this value
|
|
but then resets its value to num. Execution is aborted if
|
|
evaluation of an error value if this makes errcount > errmax.
|
|
An error message displays the errno for the error.
|
|
|
|
EXAMPLE
|
|
> errmax(2)
|
|
0
|
|
> errcount()
|
|
0
|
|
> a = 1/0; b = 2 + ""; c = error(27); d = newerror("alpha");
|
|
Error 27 caused errcount to exceed errmax
|
|
|
|
> print c, d
|
|
0 0
|
|
|
|
Here global variables c and d were created when compiling the line
|
|
but execution was aborted before the intended assignments to c and d.
|
