Example:

uLIST

10 FOR I=1 TO 10

20 PRINT I

30 NEXT I

40 END

READY

uCALL 8 :REM DISABLE INTERRUPTS

uPROG

uREADY CALL 9 :REM ENABLE INTERRUPTS

uROM 12

READY

uLIST 10 FOR I=1 TO 10

20 PRINT I

30 NEXT I

40 END

READY

In this example, the program just placed in the EPROM is the 12th

program stored.

Important: If you exceed the available PROM space, you cannot

continue programming until it is erased. In some cases you can alter the

previously stored programs. Be sure to use CALL 81 to determine

memory space prior to burning. See section 5.3.13.1 below.

5.3.13.1 User PROM Check and Description – CALL 81

Use CALL 81 in command mode before burning a program into

PROM memory. This CALL:

determines the number of PROM programs.

determines the number of bytes left in PROM.

determines the number of bytes in the RAM program.

prints a message telling if enough space is available in PROM for

the RAM program.

checks for a valid PROM if it contains no program.

prints a good or bad PROM message. A bad PROM message with

an address of 00xx indicates an incomplete program.

No PUSHes or POPs are needed.
