program execution speed as library vs variable HP50G

[snrowe]

Hi,

I've been working on porting a program that I wrote for the HP48SX to the other 48/49/50G calculators and noticed some strange behavior running the program as a library from the non hp48SX calculator models.

The main issue is when the program is run as a library on the G series calcs execution time slows down drastically opposed to running the program as a variable or as a library on the 48SX. I tracked down the slowdown of the program to the execution of the 'MEM' command. I tried using the SYSRPL version of the command that doesn't force GC and the program ran at normal speed but the memory reported was no longer accurate. I find it odd that the program runs at normal speed when the variable form of the program is executed, but has trouble being run as a library.

Can anyone shed light on what might be causing this? Any work around for executing MEM from a library program without a major slowdown?

Any insight on to what causes this would be greatly appreciated.

Thanks,
Scott
