Hi ALL!
Since on my LoView Suite I use ARexx port to communicate between programs I need some help on managin ARexx(I dunno nothing or quite nothing of ARExx...).

The problem was that:

I send command thorught ARexx port and use ' character to enclose the Rexx line...but if in the filename I have another ' the line was truncated and get an error...

How I can solve that issue? Can I parse file name and add some special character to have Rexx recognize te correct/entire line? Anything else to do?

Thank you!

You may need to pre-process the string and insert an "escape" character or use " instead of ' or ` characters.

I recall using ' characters and " characters in string handling for writing rexx scripting on my own system some years ago

If that is any help?

@Tuxedo

Can you expand a bit on your problem, perhaps with a specific example?

how are you sending the command?

Sometimes you simply can't get the right combinatin of quotes etc if you are testing from the command line with C:rx so have to write a test script

@all

the syntax was that:


SendRexxCommand("LOVIEW_THUMB_VIEWER", "'THUMB " .. file$[StartFile] .. "'")


LOVIEW_THUMB_VIEWER was the ARexx port of the program where I send the command

THUMB was the ARexx command I send

and the other was the file where I start read from...

I use the "(double quote) and the '(apices) to concatenate a full line to pass to the other program...

AFAIK ARexx needs ' to concatenate a full line like " to concatenate a full line on CLI...

@Tuxedo

I don't recognise the SendArexxCommand function is that a Hollywood command?

Have you simply tried it without any single quotes?

A lot depends on how that command sends the command onto ARexx but normally Arexx commands are sent as a single string so there would be no need to add the inner single quotes.

@Tuxedo

In ARexx you can use ' or " to delimit strings as you like.

To create a string which contains a single apostrophe, you can write either "'" or ''''.

To create a sting which contains a single double-quote character you can write either '"' or """".

@thomas

that's exactly what I looknig for THANK YOU! :)

Only one thing...dont was '''' but '' to parse the apostrophe, if I use 4 that I get 2 ' in the parsed text, but with 2 ' was ok :)

Thank you all for replying! :D

What I wrote is correct. I'll try to explain it in other words:

If the string is delimited by apostrophes you can use quotation marks in the text but if you want to use apostrophes, you need to duplicate them.

text1 = 'Mike said "This is Tom''s house".'

text2 = "Mike said ""This is Tom's house""."
