RPBASIC-52 PROGRAMMING GUIDE

2-85

POKEW

Syntax: POKEW segmen t,address,d ata

Where: segment = 0 to 7, specifies the 64K segment

address = 0 to 65535, location in segment to save to

data = 0 to 65535, number to save to RAM

Function: Writes an unsigned 16 bit number to RAM.

Mode: Command, Run

Use: POKE W1,AD,DA

Cards: All

DESCRIPTION

Use POKEW to write 16 bit numbers into RAM. The results of an A-D conversion, for example, can be

saved.

WARNING: RPBASIC-52 does not check the address. It is possible to poke into the program, stack, or

variable areas. Results are unpredictable. Poke into mem ory above MT OP for safest

operation.

See the POKEB command for segment and address information.

PEEKW

ERRORS

BAD SYNTAX If W, segmen t, address, or data is missing.

BAD DATA If segment is > 7, address or data > 65535 or negative

EXAMPLES

The following example takes data from the AIN function and saves it to segment 1 of the 128K RAM.

1000 FOR N = 0 TO 7

1010 POKE W1,N*2+100,AIN(N)

1020 NEXT

The next example prints out the data from RAM.

500 FOR N = 0 TO 7

510 PRINT PEEKW(1,100+N*2)

520 NEXT

1 2 ... 99 100 101 102 103 104 105 106 107 108 109 ... 162 163
