 Posted: Sun Jan 14, 2024 2:10 am Post subject: Wrong line numbers in error report |
 |
|
The test program below uses the array p_NQ on line 30 before it has been defined. The error is reported to occur on line 20 by SDBG64 and on line 23 by SDBG.
Breakpoints are not accepted on line 22 and 24 to 32. More generally, no breakpoints are allowed inside WHERE blocks.

This failure has been fixed for the next release of FTN95. In the current release the report of an undefined variable occurs one line too early.
By design, FTN95 treats the debugging of a WHERE construct as a single statement and the same is true for other whole array constructs. This means that the embedded undefined value ought to be reported as you step over the WHERE construct and this has now been fixed. |

| Were missing breakpoints also fixed? |

Dan
If you are referring to a bug that was reported of a different thread then you should look there for a response. |
