Creating a simple filter

(1/1)

John Hickey:
On the newsgroup, Steve Ellis asked:

How do I code a simple browse filter like

TRI:TABLETYPE='P'

Sean Cameron (CapeSoft) answered:

The entire filter expression is a string, so you need to double up your quotation marks, or use ASCII 39:

'TRI:TABLETYPE=<39>P<39>'

or

'TRI:TABLETYPE=''P'''

Using the ASCII code is a nice way of doing it as it can be a lot clearer, especially when you have a long expression with a number of string literals.
