Given this code:
#!/usr/bin/rexx
t1 = .test1~new(30)
say t1 ':' t1~string ":" t1~class
say
say '-'~copies(80)
say
t2 = .test2~new(45)
say t2 ':' t2~string ":" t2~class
exit
::class test1 public subclass string
::method init
self~init:super
if (self+0)~datatype\='NUM' then do
raise syntax 93.904 array(1,self)
end
self~objectname = 'a Test1'
::class test2 public subclass string
::method init
self~init:super
if (self)~datatype\='NUM'then do
raise syntax 93.904 array(1,self)
end
self~objectname = 'a Test2'
... and this result:
D:\Projects\Scripts>test
30 : 30 : The TEST1 class
--------------------------------------------------------------------------------
27 *-* raise syntax 93.904 array(1,self)
7 *-* t2 = .test2~new(45)
Error 93 running D:\Projects\Scripts\test.rex line 27: Incorrect call
to method
Error 93.904: Method argument 1 must be a number; found "45"
I'm curious why, in test2, 45 is considered not to be a 'NUM'.
