ASCII Instructions 369
When instructions are removed from the ASCII queue, the following bits
are set: ER = 1, RN = 0, EU = 0, and ERR = 0x0E.
AIC - ASCII Integer to
String
Instruction Type: output
The AIC instruction converts an integer or long word value (source) to an
ASCII string (destination). The source can be a constant or an address.
The source data range is from -2,147,483,648…2,147,483,647.
Addressing Modes and File Types can be used as shown below:
AWA - ASCII Write with
Append
Instruction Type: output
Use the AWA instruction to write characters from a source string to an
external device. This instruction adds the two appended characters that
you configure on the Channel Configuration screen. The default is a
carriage return and line feed appended to the end of the string.
