Hi folks,
I have made another change to CLASSLIBA that is possibly worth mentioning:
http://wiggio.com/yui/folder/stream_file.php?doc_key=ck73Bdku6hyAO+SzuM5KN0kYaKtjKAlqhvXG7mwovhQ=
The change allows arrays to be passed as arguments to methods (as is normal for other functions and procedures). For example, the following code does not work with CLASSLIB:
Code:
INSTALL @lib$ + "CLASSLIB"
DIM Class{method1, method2}
PROC_class(Class{})
PROC_new(Obj{},Class{})
PROC(Obj.method1)
PROC_discard(Obj{})
END
DEF Class.method1
LOCAL a%(), A%
DIM a%(10)
FOR A%=1 TO 10
a%(A%) = A%
NEXT
PROC(Class.method2)(a%())
ENDPROC
DEF Class.method2 (a%())
LOCAL A%
FOR A%=1 TO DIM(a%(),1)
PRINT a%(A%)
NEXT
ENDPROC
I have also added a tiny bit more syntactic-sugar, but you can easily delete anything you find unnecessary.
Thanks
Andy

Hi folks,
I found a bug immediately after uploading, so have deleted CLASSLIBA for the time being, and will upload it again later after its fixed.
Thanks
Andy

In case you thought otherwise, the inability to accept array parameters is a bug, not an intentional 'feature' of CLASSLIB! Clearly it needs to be rectified in the 'official' library, rather than being treated as an 'extension'.
I have therefore corrected CLASSLIB.BBC to accept arrays as formal parameters of methods. Version 0.95 may be downloaded from here.
Richard.

Here is CLASSLIBA with it's spoonful syntactic-sugar:
http://wiggio.com/yui/folder/stream_file.php?doc_key=phUocicEhoLWSL0X5QClkwa8dRM+l0mRNT8+YQV1wfc=
Before uploading, I solved the issue with the same method, only implementing a FOR loop. Before that my failed attempt used INSTR thinking that I could achieve better performance, but it created some delicate situations. Now having now seen your solution, I have copied it as its more elegant, and it keeps CLASSLIBA fundamentally identical to CLASSLIB.
Many Thanks
Andy
