if statement against MV variable

[drdanny]

all,

I am on D3 7.4, AIX 6.1.

when I perform an if statement against a multivalued variable, testing for the existence of nothing, if there are value marks, there is something there though no meaningful data.  is there a clean way to handle such an obstacle?

thanks,

drdanny

field2test = WHATEVER<1>

convert @VM to "" in field2test

if field2test = "" then ;* really blank unless you need to cater for @sm
