Hi I have a problem with a LookUp

[Giuseppe]

Hi I have a problem with a LookUp. It gives me an error for the "_" for the end of the line.
The mcu is a 12f629
Thank you

Return

I'll put the example below.

Strange. The manual says that you can omit the underline for certain commands, LookUp being one of them but it doesn't then see the second and subsequent lines. I think this is one for Les.

That is strange. I compiled the code for a 18F25K20 (Amicus board) without the line extension _ character and it appears to have correctly created the data table with all 255 bytes.

This is a bit of an anomaly. It should have recognised the ',_' and the ',' as the line extension. However, it appears that some are not recognising the ',_' anymore, but do recognise the ','. I'll look into it ASAP.

I am trying to get rid of the ',_' in the compiler's syntax and just make it a ',' and that is why I had it recognising both for backward compatability, but something has gone wrong somewhere in some commands.

Works fine.

Thanks everyone I removed "_" and it compiles without problems

In most of the languages the line continuation is guarantee when it's enclosed within parenthesis. But like C & Co., there's the \ symbol as line join, which is becoming less used.
The languages are evolving, spoken one too, so it's natural this changes may be breaking the backward compatibilities.
