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
