When printing an error, calc used to print the errnum (error number):
; 1/0
Error 10001
Calc now prints the errsym (errsym):
; 1/0
Error E_DIVBYZERO
Added errsym E_LN_3 for ln(0).
Added errsym E_LOG_5 for log(0).
Added errsym E_LOG2_4 for log2(0).
Added errsym E_LOGN_6 for logn(0,base).

NAME
|
|
scan - scan standard input for possible assignment to variables
|
|
|
|
SYNOPSIS
|
|
scan(x_1, x_2, ..., x_n)
|
|
|
|
TYPES
|
|
x_1, x_2, ... any
|
|
|
|
return integer
|
|
|
|
DESCRIPTION
|
|
When input is from a terminal, execution is halted and input is read
|
|
until a newline is entered. Strings of non-whitespace characters
|
|
are evaluated in succession and if the corresponding x_i is an lvalue,
|
|
the resulting value is assigned to x_i. If the number of strings
|
|
read exceeds n, only the first n strings are evaluated. If the number
|
|
of strings is less than n, the later x_i are ignored.
|
|
|
|
EXAMPLE
|
|
; global a, b, c, d;
|
|
; scan(a, 0, c, d)
|
|
; 2+3 b=a^2 3+4i 3+"a"
|
|
; print a,b,c,d
|
|
5 25 3+4i Error E_ADD
