Hello Ardash,
thanks for looking for a better description.
This online help does not correctly describe the command syntax yet
which is:
askenv name [message ...] [size]
=> askenv foo
Please enter 'foo': abcdefgh
=> echo $foo
abcdefgh
=>
=> askenv foo 4
Please enter 'foo': abcdefgh
=> echo $foo
abcd
=>
=> askenv foo msg1 msg2 msg3 3
msg1 msg2 msg3 abcdefgh
=> echo $foo
abc
=>
=> askenv foo msg1 msg2 msg3
msg1 msg2 msg3 abcdefgh
=> echo $foo
abcdefgh
=>
The logic needs some explanation. The last parameter is used as size if
it can be converted to a decimal number. In most other commands we
expect a hexadecimal number.
We started adding man-pages for all commands to doc/usage/. Do you want
to give it a try?
Best regards
Heinrich
