std-getangle | ![]() |
STD-GETANGLE is basically the same as (INITGET ...) (GETANGLE ...),
STD-GETANGLE-DEG accepts and returns degrees instead.
If a lisp function given at the prompt returns a valid type this one is accepted.
The additionally needed INITGET initialization and default value check may be omitted, thus leading to easier looping code.
If the default argument is given (and it is not nil and the flag contains no bitvalue 1), then empty input is allowed as well.
flag: integer, same as the INITGET flag or nil
kwd: a initget-like string or a list of strings or nil
msg: a string to be displayed as a prompt or nil.
def: a default value as number, either interpreted as radians (0-2ð) or degrees (0-360) or nil
bpt: a point from which the rubberband is drawn, and if a point is entered, from which the highlighted line is drawn or nil. If not nil only one point or a number is required. If nil a number or two points.
Either the default value or any number entered by the user, interpretable as radians (0-2ð) or degrees (0-360).
Interrupts the program flow, prints the formatted message and waits for user input.
