You'll need to ensure that your precompiler command doesn't otherwise cause a syntax error. You'll therefore need to include and #endif as below: If mode =1 then code code Elseif mode=2 then code code #IfDEF bad Elseif mode=3 then code code #endif endif; Steve Shimp Maintenance & Systems Engineer ExxonMobil Paulsboro Lube Plant Phone: (856)224-5059 Cell: (609)820-8501 Fax: (856)224-5030 Email: steve.shimp@xxxxxxxxxxxxxx Ken.E.Moore@xxxxxxxxx om To: foxboro@xxxxxxxxxxxxx Sent by: cc: foxboro-bounce@freeli Subject: [foxboro] HLBL question sts.org 01/06/04 08:01 AM Please respond to foxboro Hi folks, Can anyone tell me if the following code will work okay? Don't worry about syntax errors etc, my main question is about the If defined , in the middle of the if statements.
