Is there any way I can I can harness more memory for malloct()? currently I can only get between 4 & 5 K even though TealMembrain tells me there is 190K free with the largest block being 171K.

did you consider the fact that in PocketC, behind the scenes, each variable is actually a struct, i.e. takes up more space than you would expect? This holds true even for simple int's or char's. Multiply 5K of variables with (I believe) 5-6 bytes per variable, then you end up with close to 32KBytes of allocated memory; and to my knowledge this is somewhere close to the maximum chunk that standard PalmOS can allocate.

The memory reported as being free is storage RAM, which is different from dynamic RAM. Dynamic RAM is the memory that can be allocated and used from a Palm program. Older devices (which I assume yours is if only 190K of storage RAM is free) has ridiculously small amounts of dynamic RAM, sometimes lower than 32K.
