Re: Character strings

James,

If you can update to 5.1.1,
then you can use str_right_strip(str) to strip off any white-space at
right.
Or. str_left_strip to strip left end white space, or str_strip to
strip off
white space at both end.

For example, with 5.1,1,

you have
str1 = "abc "

str2 = str_ritgh_strip(str1)
and str2 will be "abc".

ncl 7> str1 = "abc "
ncl 8> print("<" + str1 + ">")
(0) <abc >
ncl 9> str2 = str_right_strip(str1)
ncl 10> print("<" + str2 + ">")
(0) <abc>
