I use J504 on a PowerBook with OS V 10.4.7 in German language.
Can I do something that allows German "Umlaute" like ä and ü in J code?
Does a key combination exist which interrupt an endless loop without
closing J?
I know how to handle an error situation with the control words "try"
and "catch". I tried to use the verb "Adverse" for the same purpose
but did not succeed. The example in the dictionary on page 159 is too
cryptic for me. I would appreciate examples for "Adverse" to handle
error situations which are easy to understand.
Are there J packages or labs which include more comprehensive
collections of statistical functions?
Can you recommend a handheld without a phone module, on which the
Pocket PC-version of J is operational?
Best regards
Heinz Schild
