Hello,

My problem is related to a TDS48GX surveying program running on an HP48GX calculator. This program has a function called RCLPT. This function should access the TDS database from the calculator's operating system and should return the coordinates of a certain point. This function should be run after exiting the TDS48GX application, from the HP48GX calculator's operating system. I'm following the steps according to TDS48GX User's Manual but I'm getting an error "Insufficient Memory" instead of the coordinates. I have about 60KB available in port 0. I tried installing the application on another HP48GX calculator and got the same message. I thought the card might be wrong. Otherwise the card is working fine, everything runs fine from the inside of the application but when I quit it doesn't run the functions from the calculator's operating system. I looked on another TDS48GX application running on an HP48GX belonging to a surveyor that I know, another card and another calculator and I got the same message. At this point I cannot believe that two  different application cards, both working fine from the inside of the application can have exactly the same thing broken and giving exactly the same symptoms when run from the calculator's operating system. Maybe I'm doing something wrong. I need the coordinates produced by TDS application to be accessed from the calculator's operating system through RCLPT function in order to use them with some programs that I want to write to solve some particular surveying problems. Can anybody help me to solve this problem ? The coordinate files imported and exported by the application with extension .CR5 are in fact csv files. Does anybody know how to open and retrieve information from a csv file on an HP48GX calculator ? What programming language should be used ? Any examples of code ?

Thank you for looking at my post

Hello Iuliu,

What directory are you in when you exit the TDS program? If you are using a hot key to exit the program you should be in the correct directory. Make sure you are supplying the correct parameters to the RCLPT function. Make sure the point number you are trying to recall is an existing point number.

Regards,

Mark

Hello Mark,

Thank you for your help. I realize now that every time I was trying to run the function I was in HOME directory. After your advise I changed the directory to tds.48. Everything worked fine. If the point you are asking for is not in the file the function returns -99999.99 for all N, E and elevation but it does not crash. So this is the correct answer. You saved me a lot of time spent in searching the net.

Thanks again, Iuliu

Hello Iuliu,

Glad I could help! Now that we have that problem solved, we can move on to working with the CSV files. Do you want to work with the files after you export them to a computer? Do you have the TDS Survey Link program on your computer?

Regards,

Mark
