ACB(channel, control, ) - reports the numbers of ASCII characters in buffer

ACI(string, dest) - convert ASCII string to integer

ACN(string, string,dest) - concatenate strings

AEX(string, start, length, dest) - this will cut a segment of a string out of a larger string

AIC(integer, string) - convert an integer to a string

AHL(channel, mask, mask, control) - does data handshaking

ARD(channel, dest, control, length) - will get characters from the ASCII buffer

ARL(channel, dest, control, length) - will get characters from an ASCII buffer

ASC(string, start, string, result) - this will look for one string inside another

AWT(channel, string, control, length) - will write characters to an ASCII output
