Arexx Escape Codes

Hello,

The following command sent to an Arexx Port is accepted:

ADD DATESTRING '"Wednesday 30 November 2011"' ENDDATESTRING '"Wednesday 30 November 2011"' TIME '"11:00"' ENDTIME '"12:00"' TITLE '"lunch break"' NOTE '""' REPEAT '"1"'

But if wanted to change 'lunch break' into for example 'mum's birthday' or even add "hello" into the notes.. how do I do this?

In other words how do I correctly escape single quotation and regular quotation marks?

I tried backslashing single quotation and regular quotation marks, but wasn't successful.

/**/

say " test""ing"

say ' mums''birthday'

i have been struggling with this more than once in the past

Quote:

also:

say 'test"ing'

say "mums'birthday"

will work if there isn't an insane level of quotes already.

@ Chris
True, but I think looking at the quoted command that was the situation. Too many quotes...

Actually I found that by experimentation, couldn't remeber it either.

Well I have success escaping single quotation marks by simply escaping it with another.

No luck with double quotation marks - so instead double quotation marks are treated as single quotation marks and escaped that way which is satisfactory.

It should work with double quotes too, my test above did.


BTW your quoted code above can get you inot difficulties if any variables accidentally cooincide with the terms




would be better as



(NB the whole string is srrounded by sigle quotes not just the arguments)

in your above 'ADD' 'DATESTRING' etc etc will get replaced by any variable in your script with the same name. Either you have to be very careful about variable name choice or simply quoting the command saves the risk.

You can also use d2c() to accomplish this.

You can also define a single quote or double quote

SQuote="'"
DQuote='"'

..if you wanted to, but escaping it with another quote of the same type works fine for me too.

SAY 'Mum''s' = Mum's
SAY "Mum's" = Mum's
SAY 'Mum"s' = Mum"s
SAY "Mum""s" = Mum"s

(Didn't test it, but that should be correct)
