TDS48GX running on HP48GX RCLPT function error |

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 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
