Add LEFT$ and RIGHT$ String functions

Message

This compiler is better than most, partially because it handles strings. It would be nice to add the common BASIC 'left$' and 'right$' (and maybe even 'mid$') string functions as well.

Hi,

are you referring to functions ltrim and rtrim
(left trim and right trim)?
If so it will be implemented in new PRO version of our compilers for PIC

Regards

Yes. That's them! Thanks.

The basic functions Left$ and Right$ return a number of characters at the beginning resp. the end of the string, while "trimming" is removing spaces at the beginning resp. the end of the string. So the functions are (I think) totally different.

I didn't realize trimming referred exclusively to spaces. If that's the case, then the ability to CHOP spaces or characters from a string's LEFT and RIGHT end would be far more useful, at least to me. I didn't understand the space-only distinction.

Like been said earlier, we will implement ltrim and rtrim functions in new PRO version of our compiler for PIC. We are working on this right now.

Hi,
Left$, Right$ and Mid$ are all special cases of the "Copy" function in http://users.edpnet.be/rosseel01/DRO/PI ... Utils.ppas. In Pascal, but the code can easily be converted to Basic...

PRO VERSION of compiler?

What is this?

Hi,

maybe you were not aware that we started releasing PRO versions of our compiler.
This is already done for our AVR compilers, (you can find it on this forum in AVR section).
The main features are new bit variables and new graphic IDE.
We expect beta versions of PRO version compilers for PIC family to be released in January.
When this happens (there will be an official announcement) you are all welcome to test it.

Regards

This leads to the next question - will registered owners of MEbasic ver. 7 have to pay for the PRO version?

I notice that the AVR PRO version is more expensive then the standard, so I guess it is a separate (and more expensive) version.

Hi,

this is a management issue that is still "on the table"
being decided. When we are little closer to release of new PRO compilers
for PIC we will have an answer to this question.

It is separate version for AVR because when we make official release of all three compilers for AVR
(C, Pascal and Basic), the old versions of AVR compilers will become obsolete.

Can you please summarise the main differences between the new PRO compilers and the old ones, as a comparative list?

#14 Post by **marko.ziv** » 23 Dec 2008 14:13

Hi,

in short notes two main differences between old version and a PRO version is that in the PRO version we have introduced bit variables, and new graphical IDE (as already seen in compilers for 8051 and AVR family of MCUs).
We are very optimistic about bit variables because tests have shown that compiler produces 30-40% less machine code (if you compare the same code in new compiler with the old one).
New IDE has a lot of new features and many improved old ones, library manager (with a simple click you you enable/disable the given hardware library for your project) and many more.
Hope this helps.

Regards

It looks like ltrim and rtrim never made it.

Add LEFT$ and RIGHT$ String functions

Add LEFT$ and RIGHT$ String functions

After 4 years, no ltrim or rtrim?
