If I have a line of code that's 150 characters long, is there a way to continue that code onto the next line so all of the code can be viewed on my screen without scrolling to the right?

Re: Wrapping code
Hi there,
yes there is...
just use the _ to break the line.
Check this example:

I'm not sure that works on anything other than the example.Originally Posted by ruijc

Re: Wrapping code
Maybe you could phrase that the other way around, and suggest a scenario where it doesn't work?

Re: Wrapping code
I thought the maximum allowed number of constants for LOOKUP was 255, it looks to be way more than that it the list - has that changed?
Never the less, it does show the "line continuation".

Re: Wrapping code
OK, I'll do my best to clarify that myself.....
Previously the limit was 255 or 256 but in version 2.5C the limit for PIC18 parts was increased to 1024 entities. The PBP3 manual (which of course is the correct place to look when in doubt) says 1024 for PIC18 parts while the online help in MCSP 5.0.0.3 doesn't mention that, it says 256 for 18C parts though.

Re: Wrapping code
While the manual doesn't say a lot about how to use the line extension character, from experience you need to extend from an operator and not just anywhere in the line.
For example:
myvariable31 = myvariable1 + myvariable2 + myvariable3 +_
myvariable4 + myvariable5
should work.
However;
myvariable31 = myvariable1 + myvariable2 + myvar_
iable3 + myvariable4 + myvariable5
will not.
It's called a line extension, but it's really statement extension to include terms and operators on the following line. You can't just jam it anywhere in the line of text and have the next line pick up exactly where the first left off.

Re: Wrapping code
My bad. Pleased to see it works OK.

I can't code wrap when the characters extend past column 255 even though we're given 1024.
