I am more on the side of jgt in this matter: you can teach almost everything except the "mental environment" to make the learning experience take place - which is why idiots are quite resistant to education. And i have to disagree with sea: diplomas tell something about a persons industriousness (there is no convincing translation for the german word "Flei�", but this would describe it best) but nothing about the learning capability.

I have no diploma at all in computer sciences or any related area (i am actually a musician) but still can hold my own in front of a keyboard, more or less. ;-))

I think a requirement for a prospective electronics engineer is a good command of some basic and intermediate math and the ability to quickly estimate orders of magnitude. I have often seen people using calculators for even the simplest calculation and not even flinch when results were way off because of typing errors. i.e. i would need some time to calculate "10 / 7" but i can immediately estimate it to be "1.5 or thereabouts". I simply know "15" to be wrong and ".15" to be wrong either. This is not a matter of relying on technology or not (i'd use a calculator too if i want a precise result), it is a matter of being willing to exert some mental effort for getting an (even limited) result.

Here is a test question, no tricks involved and the answer can easily be calculated once you know what to calculate. Take your time in solving it:

Suppose you have a melon, which weighs 100kg. 99% of it is water. Now, this melon lies in the sun for some time and some water evaporates, so now it is is down to a water content of 98%. How much does it weigh now?

Most will, without thinking, say "99 kg" or something near this value. But "99%" and "98%" are not from the same base, yes? Here is a hint: What would be 100% when 1kg is 2%, hmmm?

/PS: on second thoughts: knowing the limitations of ones knowledge is an even more critical skill. Suppose the following situation: places A and B are roughly 100km apart. You go with your car from A to B maintaining an average speed of 71.047 km/h. Question: how long will the drive take? One usually gets an answer "exact" down to the nanosecond, completely ignoring that "roughly 100km" hardly justifies anything more precise than quarter-hours.

XmListReplaceItemsPosUnselected(library call)							     XmListReplaceItemsPosUnselected(library call)

NAME

       XmListReplaceItemsPosUnselected -- A List function that replaces items in a list without selecting the replacement items

SYNOPSIS

       #include <Xm/List.h>
       void XmListReplaceItemsPosUnselected(
       Widget widget,
       XmString *new_items,
       int item_count,
       int position);

DESCRIPTION

       XmListReplaceItemsPosUnselected	replaces  the  specified  number  of items in the list with new items, starting at the given position. The
       replacement items remain unselected, even if they currently appear in the XmNselectedItems list.

       widget	 Specifies the ID of the List widget to replace items in.

       new_items Specifies a pointer to the replacement items.

       item_count
		 Specifies the number of elements in new_items and the number of items in the list to replace.	This number must be nonnegative.

       position  Specifies the position of the first item in the list to be replaced. A value of 1 indicates that the first item replaced  is  the
		 first item in the list; a value of 2 indicates that it is the second item; and so on.

		 Beginning  with  the  item  specified in position, item_count items in the list are replaced with the corresponding elements from
		 new_items. That is, the item at position is replaced with the first element of new_items; the item  after  position  is  replaced
		 with the second element of new_items; and so on, until item_count is reached.
