Hot Tips from PSG: Using Nested Ifs in OptoScript

OptoScript

Opto 22's Product Support Group (PSG) develops some helpful tips as they work with customers who contact them for free product support.

"Recently while compiling some OptoScript code, I got the dreaded 'syntax error' on lines 92, 96, 102, 106,..." one PSG engineer told OptoNews recently.

"Since I've made this mistake before, I suspected the root cause of all these errors was a missing endif in my nested ifs."

If you use if statements nested within other ifs in your PAC Control OptoScript blocks, here are a few tricks to help you keep track of which if goes with which else and/or endif.

  • Type the else (if applicable) and endif immediately after typing your if/then line, and then fill in the code between them after that. That way you know they're all in place.
  • Use comments. Especially when you anticipate a lot of code between the if/else/endif, it may be helpful to add comments after each, such as:
    else // the opening of the comm handle failed
    endif // checking the comm handle open return value
  • Indent lines of code as shown in the PAC Control User's Guide section on OptoScript Control Structures. Then you can use the column number to match an if with an else or endif. Put the cursor just in front of one, note the column number, then look for the other half of the pair in the same column.

What if you still get that series of syntax errors? Watch for more tips in the next OptoNews.
