Re: [netrexx-pipelines] Indexed strings with multiple indices and the exists() method

[Marc R. <re...@gm...>]

Hi Leslie,

by defining list[level1, level2] you do not define list[level1].
if you want to check existence of level1, you must assign it a value.

Check the following:

a=''
b=''
a['level1', 'level2']=1
b=a['level1']

if a.exists('level1') then say 'a[''level1''] exists'
if b.exists('level2') then say 'a[''level1'', ''level2''] exists'

a['level1'] = 1
if a.exists('level1') then say 'now a[''level1''] exists'


I think that is consistent with classic rexx's stems.
