Memory couldn't be read at.....

[GCC Consulting]

I ran into this error today after making some changes in a program I have been
working on.

The program passed the syntax check and didn't have any runtime error messages
appear when the program started.

After a bit of tracking and the use of the debugger, I finally found what was
causing the crash.

I had changed a standard browse lookup statement created by the lookup wizard to
its component parts.

ba="(brw=15 xkey=XSUDFA show=pkeep pop=ERN mlen=8 fill=asc,top)"
bb=bb="[\b5Ord# Item#        DESCRIPTION               Quant   Order    Shipped
\a-"
bc= bc="*1     *2    *3                                       *4    *5"
Lookup foobar k=1  i=d  -nxm b=(ba&bb&bc)

The only problem was the I had left off the closing ] on bb=.  As the actual
line was wider the 80 characters, I didn't notice the missing close bracket.

The program ran fine until it hit this browse lookup and then crashed with the
memory read error.  When I narrowed down where the crash was taking place, I
placed a debug just before this browse was executed and was able to locate the
problem.

Although this is my error, and Ken will most likely disagree with me, I would
think that either the syntax check or the normal runtime check would have found
this error.  Or at least find a better way to handle this error without crashing
the program with a memory read error.

This is one reason why I posted to the wish list, a request to have the browse
lookup wizard have an option to create these code lines, if wanted or when the
browse lookup being created would exceed the 2 line maximum.
