Display string issue

The attached flowchart should take an integer value of 267 and display 26.7
Flowcode simulator shows:

Hardware is the same as real pic which shows:

Not sure why only the last byte of the string is displayed.
I'm hoping to save some memory and use:
Code: Select all
Temp_String = Left$ (Temp_String,2) + "." + Right$ (Temp_String,1)

Hi Martin,
Thanks for the detailed bug report.
We do have some known problems with the generated target code for string concatenation (mainly due to memory constraints on target and the use of temporary buffers)
I’ll try and raise the priority of this issue.
In the meantime, the workaround is to avoid multiple concatenations on the same line
Code: Select all
Temperature = Left$ (Temp_String,2)
Temperature = Temperature + "."
Temperature = Temperature + Right$ (Temp_String,1)
I think your other example
Code: Select all
Temp_String = Left$ (Temp_String,2) + "." + Right$ (Temp_String,1)
would be even more tricky, as it would require more internal buffers, but I’ll add this issue to the bug log as an interesting challenge
Regards,
Leigh
