Example:
An 8 point positive Ramp down loaded into wave 1, address 0.
WVFM:WAVE 1;MEM 0,#40016 binary_data \n
Where binary_data are the following values as bytes sent to the GPIB or
RS-232.
|128|0|146|73|164|146|182|219|201|36|219|109|237|182|255|255|
The complete command as bytes in memory would look like the following:
|'W'|'V'|'F'|'M'|':'|'W'|'A'|'V'|'E'|' '|'1'|';'|'M'|
|'E'|'M'|' '|'0'|','|'#'|'4'|'0'|'0'|'1'|'6'|128| 0 |
|146| 73|164|146|182|219|201| 36|219|109|237|182|
|255|255| 10|
Where |'A'| represents one byte in memory containing the character 'A' (i.e the
value ASCII(65)) and |219| represents one byte in memory whose value is 219.
Therefore: |'A'| and |65| are equal in value.
In QuickBASIC
A$= "WVFM:WAVE 1;MEM 0,#40016"+CHR$(128)+CHR$(0)
+CHR$(146)+CHR$(73)+CHR$(164)+CHR$(146)
+CHR$(182)+CHR$(219)+CHR$(201)+CHR$(36)
+CHR$(219)+CHR$(109)+CHR$(237)+CHR$(182)
+CHR$(255)+CHR$(255)+CHR$(10)
In C
{
int i;
char wvfm_buffer[100];
char data[16]= {128,0,146,73,164,146,182,219,201,36,219,109,237,182,255,255}
sprintf(wvfm_buffer,"WVFM:WAVE 1;MEM 0,#40016");
for(i=0; i < 16; i++)
wvfm_buffer[i+24] = data[i]; /* 24 bytes in header */
wvfm_buffer[16+24] = '\n'; /* end of block */
