Problem when using conditions

tomanT9U6N — Fri, 07 Jul 2023 10:38:35 GMT

Hello, can someone explain to me why the IF condition cannot be used in this code?

The time.txt file contains only the number 1688722295

Interestingly, if I delete the IF condition in this code, the program will work.

FILE OPEN "time.txt" FOR READ AS "inp" INT $read_seconds = 0 FILE READ $read_seconds FROM "inp" FILE CLOSE "inp" INT $diff = time() - $read_seconds IF $diff > 60 { MESSAGE INFO $diff }

Try this, enclose the condition to be checked.

FILE OPEN "time.txt" FOR READ AS "inp"

INT $read_seconds = 0

FILE READ $read_seconds FROM "inp"

FILE CLOSE "inp"

INT $diff = time() - $read_seconds

IF ($diff > 60) {

MESSAGE INFO $diff

}

I've tried and still get the error: unsupported element or command

Works for me, after i put the full path to time.txt in

i.e

FILE OPEN "C:\Users\KevinHammond\Desktop\time.txt" FOR READ AS "inp"
INT $read_seconds = 0
FILE READ $read_seconds FROM "inp"
FILE CLOSE "inp"

INT $diff = time() - $read_seconds

IF ($diff > 60) {
MESSAGE INFO $diff
}

Thank you then it is not a bug in the code, but in my computer.

Make sure the file is not located in folder that doesn't have read/write access like in "Program Files" or something.

I'm really confused now. Why does this work with the quotes at "inp" and another recently issue did not?

Writing data to the file and reading data from the file works. The macro error occurs when I insert an arbitrary condition in the code. 🫤

@old_snickers Hi. You don't actually need the double quotes around inp, given that this is a single word without spaces.

See the extract from the Macro Programming Guide below, which shows an example of defining so-called file handles without any quotes:

You can find the latest version of the Macro Programming Guide here: https://www.autodesk.com/support/technical/article/caas/tsarticles/ts/26zXUqtRe1Tur1KdK1pctn.html

(scroll down towards the bottom of the page).

@tomanT9U6N Hi. Unfortunately, I also can't reproduce your error. You might try using the 'macro debugger', it might give a clue to what is going wrong.

You invoke this by:

macro debug <path-to-macro-file>

I hope that will help.

I more item to check....

Is the macro being run from from a trusted files or trusted directory, i have seen macros questioned from time to time usually if they are stored on a network drive. check options as below.

Hope you get sorted 🙂

When I try macro debug, the whole code is displayed in one line. That's weird.

Thank you all for your help, but the problem seems to be with my PC.

1 last thing based on your last response.

what text editor are you using, i am wondering whether when you hit enter to go to the next line whether you are getting a carriage return line feed command?

I use notedpad++ but windows text editor will do, i would not use wordpad as it can give spurious results.

I have switched on these characters using..View...Show symbols

If you do not have these characters it would cause the whole macro to appear on one line

You are an absolute legend! I had the line ordering set to CR. After switching to CRLF the macro works!
Thank you very much 😊
