LOAD

Command

SYNTAX: LOAD

LOAD program

LOAD program RUN

LOAD to RAM segment, RAM address, from me mory segm ent, memo ry address, length

PURPOSE: LOAD with no parameters reads a program from Flash and puts it into RAM.

LOAD program retrieves a pr ogram from 0 or 1 in a 128K Flash E PROM or 0 to 7 in a 512K F lash

and puts it into RAM.

LOAD with all the other parameters transfers data from Flash to RAM or RAM to RAM.

REMARK S: LOAD with no parameters is the only valid LOAD com mand on the RPC -150 and RPC-2300.

LOAD n RUN is used within a program to run another program. Program execution always starts at

the first program line.

The third syntax, from me mory segm ent, refers to the physical memory map and is in the range of 0

to 15. Segments 0-7 are always RAM while segments 8-15 are always Flash EPROM . The number

of segments actually available depend upon mem ory size for ea ch type. 128K RAM uses segments 0

and 1. 128K Flash use segments 8 and 9. A 512K RAM uses segments 0-7 while a 512K flash uses

segments 8-15.

The third syntax is usefu l for moving blocks of memory around from F lash to RAM or RAM to

RAM. Using proper addressing, you can move and replace CA MBASIC arrays in RAM . Use the

SAVE com mand to store to Flash.

EXAMPLE: LOAD Loads a program from Flash segment 0.

LOAD n Loads a program from Flash segment 0 to 7

LOAD 1,weight,1,&9000,4500 Loads 4500 bytes of data to RAM segment 1, address

“weight” from Flash segment 1, address &9000.

LOAD 1 RUN Load pr ogram from Flash seg ment 1 and runs it.

ERROR: < Data negative> – for addr ess or length

< Data > 65,535> – for addr ess or length

< Data > 2 or 7> for segment
