Hi all
Again I need your help.
I am using a CMM with MMBasic 4.5
I have been adding quite a few variables to the point that I now get an error message - Error: Not enough memory

The line at which the error occurs is shown below. It's not the line, as it worked before I added the additional variables
When I remove the variables it works.
[279] Print #1,Date$,Mid$(Time$,1,5),Format$(ATT1,"%4.1f"),Format$(ATT2,"%4.1f"),Format$(ATT1-ATT2,"%4.1f"),Format$(RHM,"%4.1f");
Error: Not enough memory

At another time:
[435] LCD 1, 1, "T" + Format$(LT1,"%02g") + " B" + Format$(LT2,"%02g") + " A"+ Format$(LTA,"%02g") + " " + Format$(Mnt,"%02g") + Format$(Mxt,"%02g")' Display Top, Bottom and Average Temps
Error: Not enough memory

The memory command shows the following

> memory
20kB (59%) Program (604 lines)
8kB (25%) 60 Variables
1kB ( 3%) General
5kB (13%) Free

I appears that these variables and their use of memory are the problem.
Any suggestions how I can work around the problem?

Assuming that the problem is the line getting too complex, break it down to bite sized pieces.

temp$ = DATE$+MID$(TIME$,1,5)+FORMAT$(ATT1,"%4.1f")+FORMAT$(ATT2,"%4.1f")
temp$ = temp$ +FORMAT$(ATT1-ATT2,"%4.1f")+FORMAT$(RHM,"%4.1f")
PRINT #1, temp$;

temp$ = "T" + FORMAT$(LT1,"%02g") + " B" + FORMAT$(LT2,"%02g")
temp$ = temp$ + " A"+ FORMAT$(LTA,"%02g") + " " + FORMAT$(Mnt,"%02g") + FORMAT$(Mxt,"%02g")
LCD 1, 1, temp$

For a true 'out of memory' problem,
start by striping the comments from your code before loading.

Hi TassyJim

I had searched the forum about 'out of memory' and the shortening was suggested.
I tried that but made no difference. I then resorted to TBS.

I stripped all the comments out as you suggested and reduced the file by 25% and it worked but this will make the debugging difficult in the future.
Is there any way of keeping the comments but doing something with the variables or something else?

You can use MMEdit.
It has the option of stripping comments every time you upload and keeping line numbers aligned.

Apart from that, reusing variables can help

I had a problem with out of memory on another project using the same kit as the author of the software was using with no problems, I managed to get it working by changing the mode, The author was using mode 3 I changed to mode 2 and it worked. It was just strange that it worked fine for him even though we were using identical kit.
So perhaps this might help?Edited by skylight 2016-07-11

I found TassyJim's suggestion great.

The stripped file was half the size.
I now keep a copy of both the commented and stripped files.
I differentiate by adding nc(no comments) to the filename.
Thanks again for your support.
