Hi VM:

Noticed if one happens to miss a bracket or wrong bracket, (Suppose other errant data entry), when entering a variable to the expression window etc, the code still compiles but the expression window shows no error. Just "Waiting for Breakpoint data". Should probably show error or something to alert the suer they have entered something incorrectly.

Correct a Breakpoint "When Hit" condition. No message appears in any of the Micro output windows, unless it is a error in the spelling of a variable, it will throw  a message that it can not compile, a missing or wrong bracket shows no message.

e.g  {loop_cnt} {millis(}

Error compiling

If you spell a variable wrong it will throw a compile error, but if for example you entered a square closing bracket at the end instead of a curly bracket it will compile but the expression window will not display data and no error message to notify the user. There might be other examples that may do the same, comma, period etc.

Cheers
