You cannot change the defaults but you can override them by specifying
a string value for word's or xword's second parm.

These are the default delimiters if the caller chooses to omit
the second parm. They cannot be changed (that is you cannot
create a different set of DEFAULT values) but you can specify
any delimiters you wish by supplying the second parm.

There is a an example of doing this (and more) in my CI Programming
talk on Jazz at:
http://jazz.external.hp.com/papers/SolSymposium_03/CIProgramming_files/frame
.htm
see the notes for slide 54 "string manipulations"
Anyway, this will work:
setvar x 'what you have above'
setvar i 0
while setvar(x![i+1],word(x,,setvar(i,i+1))) <> "" do
endwhile
showvar x@
X = remote :node hello sesname,mgr/pass.account,group
X1 = remote
X2 = :node
X3 = hello
X4 = sesname
X5 = mgr/pass.account
X6 = group
X7 =
It can be refined or fine-tuned as needed.

word() first appeared in 5.5 (base) and is described at:

xword() first appeared in 6.0 (base) and is described at:
