Emmitt, Sami and Alastair:
I very much appreciate your comments regarding GOTO commands within
SWITCH blocks. During the long weekend, I was pondering over your
comments regarding why GOTO commands could be a problem within SWITCH
blocks, especially since I have not had a problem with this
situation.........yet. Then it dawned on me! The GOTO statement would
skip over the BREAK and ENDSW statements and can thus confuse the
computer which is looking for these statements to close the block. It
also dawned on me that IF blocks have corresponding ENDIF statements to
close them and (though I have never put a GOTO command in one) WHILE
loops have corresponding ENDWHILE commands to close them. Does this
mean that a programmer should not put GOTO statements within IF Blocks
and WHILE loops?
Once again, thank you very much!

Stuart,
To pick up on Albert and Sami's observations about the GOTO from a
switch block, here is how I handle that:
SET VAR vlabel TEXT = 'somelabel'
SWITCH (.vwhatever)
CASE 1
{ Some condition exists }
SET VAR vlabel = 'thisotherlabel'
BREAK
CASE 2
{a different condition exists}
SET VAR vlabel = 'yetanotherlabel'
DEFAULT
BREAK
ENDSW
GOTO &vlabel

I see two possibilities:
"IF variable = NULL THEN" should be "IF variable IS NULL THEN"
Within a SWITCH block, you should issue "BREAK" instead of using "GOTO
TheEnd".. The break will drop the programming call down to the next line
after the ENDSW line.

I may be completely wrong but I thought that GOTOs in SWITCH statements
were something to be avoided. Maybe it's that which is not working?
