Clovertechies, I am having an issue within regexp to compare a null value.
Anyone knows a solution please post. What I am trying to do
is that if the iam_18 field is null then kill it else continue.
for testing purpose I am doing as follows.
None of the values inside the braces able to check the $iam_18
value
hcitcl>set iam_18 “” <---- This is how I am setting as a null value. Eevn in the HL7, IAM:18 is blank. hcitcl>echo $iam_18
hcitcl>regexp { } $iam_18
0
Thanks in advance.
Reggie
