Looking for symbol in (symbols)

[cormullion]

How do I find out whether a symbol is an existing (built-in) newLISP symbol:

Code: Select all

(find rubbish (symbols))
;-> 204

It looks like the symbol is created first, then found.

'sym' with optionl 'nil' parameter suppresses creation and only checks existence:

Code: Select all

> (sym "rubbish" MAIN nil)
nil
> (sym "println" MAIN nil)
println
>
