Set Variable or CustomProperty Names with and expression

[dunbarx at aol.com]

"Neither of these worked."

Sure they do, or rather, they compile without issue. But the code snippets you supplied, before I fixed them, do not do much, since they contain no data to work with, and create nothing. But if you populate some of those orphaned variable references, you will get output. 


This may be purely academic...

Neither of these worked...

I took the cue from Mark and tried arrays

this
was incredibly simple... almost.

In the end I was unable to figure out how to
pass a variable string as a 
name of a custom property. My head was hurting, so
instead of breaking 
it on further attempts to find the algorithm for this... I
"man handled 
it" in the end with my usual verbose "baby xTalk"

command
getAndDistributeCategories
    set the defaultstack to "Gurudeva"
    put url 
("file:/" & localpath()& "data/gurudeva-quotes.txt") into 
gAllQuotes

   
set the uAllQuotes of  stack "Gurudeva"  to gAllQuotes # line/pipe 
delimited

put the uCategories of this stack into tCategories # tab delimited


    set
the linedelimiter to "|"
    set the itemdelimiter to tab

    repeat for
each line x in gAllQuotes

       repeat for each item y in tCategories
     
put "t" & y & "Set" into tAggregatedSet
          if (item 6 of x contains y)
then put x & "|" after aQuoteSets[y]
       end repeat

    end repeat

#
get some stats

    repeat for each item y in tCategories
       put y & "
quotes: " & the number of lines of aQuoteSets[y] & cr 
after tCountCheck
   
end repeat

    put tCountCheck into url ("file:/"& localpath() &

"data/quote-spread-stats.txt")

## LOAD PROPS - which is the target goal of
this handler ##

# I "give up" on a more efficient method.. this works but
#
has the downside of being hard-wired... so if we change the category names
# we
have to manually massage this code... there must be a better way:
# you cannot
do anything like
# set the ("u" & y & "Set") of this stack... the compiler
complains this 
is illegal

    set the uKarmaQuotes of this stack to
aQuoteSets["Karma"]
    set the uHinduismQuotes of this stack to
aQuoteSets["Hinduism"]
    set the uSivaQuotes of this stack to
aQuoteSets["Siva"]
    set the uWisdomQuotes of this stack to
aQuoteSets["Wisdom"]
    set the uLifeQuotes of this stack to
aQuoteSets["Life"]
    set the uGuruQuotes of this stack to
aQuoteSets["Guru"]
    set the uSelfQuotes of this stack to
aQuoteSets["Self"]
    set the uGodsQuotes of this stack to
aQuoteSets["Gods"]
    set the uHumorQuotes of this stack to
aQuoteSets["Humor"]
    set the uMeditationQuotes of this stack to
aQuoteSets["Meditation"]
    set the uSadhanaQuotes of this stack to
aQuoteSets["Sadhana"]
    set the uWorshipQuotes of this stack to
aQuoteSets["Worship"]

end getAndDistributeCategories

So this is the same
issue: setting variable name or CustomProp name with 
an expression.
