polling information in rs-232

As you already have the hardware uart connected to the GPS unit, I'll ask how do you have the PC connected? 4800 baud is standard for a GPS unit, so you're good there. Skimask has correctly suggested that you will find that PicBasic's Hserin command does let you accept an entire string at once, instead of reading in a single character at a time and building a string like you are trying to do. You'll have to declare an array variable big enough to accept all of the characters in your string.
I would use an interrupt to capture the incoming string from the GPS unit, and then either DEBUG or SEROUT to send the string out to the PC. There are a few serial interrupt example programs on the MicroEngineering Labs website, and there are a lot of examples on this forum, and debug and serout or serout2 are explained well in the manual.

HSERIN also lets you terminate inputting with a certain character when using the STR option, thereby eliminating interrupts.

thanks to all, it finally worked... (not as i have expected though)

what i wanted to achieve was to put all the characters in an array, but my programming skills are somehow limited for now (learning you know and HSERIN is tricky sometimes).

but i guess i'll get there eventually

i know it's a simple thing to do (for you guys or gals?) (noticed there's a Melanie with a lot of braincells around here)

i am not that bad in VB but going back a sequential way of programming is like (for me that is) going the other way around!

at 49 years old, i guess i am not that bad, just hope you all enlighten me of your knowledge somehow (but i don't want to be taken by the hand)

i am probably a NEWBIE in this pic programming but not a BEGGER who wants to have the job done by others!

So i guess i'll just keep on going on this little project of mine and thanks a lot again for the pointers.

i'll stick around.

Hi Tondunard,
Welcome from a 52 year old noobie to any kind of programming, I have been hangin' out here for about 19 months now, it is fun to revisit my earlier forrays into PBP. The learning curve seems to have a few bumps in it, but this is the place to find the straight talk.

nice to meet you sir, hope i'll find some answers to all my questions (by searching this forum)

Welcome to the forum. You got it. The way to learn is to try things and read this forum daily, not just when you have a problem. If time permits I like to work through some of the problems people have and see if I can figure them out. Just like a home work assignment.

Some of the professors here are even funny

That's just great, hope i'll be able to do that someday.

what i would like to achieve is to put a strip of data (60 characters) in a variable so that i can modify it later and resend-it every second.

Can't seem to be able to put my finger on it, but i am so close.

anyway, i'll search again (and again), and i will finally get it somehow

what i have now is a hserin (to receive) and right after that a hserout.

Putting incoming serial data in a variable is like a big miracle (lol).

Timing is my big problem for now, while i receive (hserin) i don't have time to store the data somewhere (loosing characters)

so far i made some progress, i'll get there eventually...
