Drive E
Drive E is a configurable RAM drive (up to 256K). The contents of this
drive are erased when you boot or reset the terminal or change the backup
battery. You use standard ANSI C functions to access the files on this
drive. You can store up to 128 files on drive E. By default, the RAM drive
is not configured and the memory is available for programmable (Malloc)
memory allocations. To configure the RAM drive, see “Configuring Drives
and Memory on the Terminal” on page 35.
Drive G
Drive G is an optional 2MB or 4MB extended storage drive. You can store
up to 128 files on drive G. Use this drive to store large lookup tables and
data files.
Note: On each drive, filenames are customer defined using eight characters
with a three-character extension.
Malloc or Free Memory
On the terminals, applications are customer defined. You have 512K total
RAM that you can use for the application execution space. You can also
configure this RAM to be the RAM drive (up to 256K). The remaining
RAM is the Malloc/free memory pool.
