GetC

INTEGER GetC(BUFFER_INPUT SOURCE); 

Returns the value at position 1 of SOURCE string and shifts the rest of the buffer up 
by one. In this way, values may be picked out of a buffer for processing. 

SOURCE is typically from a BUFFER_INPUT statement. It may be defined as a 
STRING or STRING_INPUT, but since GETC removes characters from SOURCE, 
the result is destructive to the source string.

An INTEGER containing a single character from position 1 of the buffer. 

If there are no characters in the buffer for GETC to retrieve, then the value of 65535 
is returned.

In this example, a buffer input is read until the character “A” is retrieved.

BUFFER_INPUT IN$[100];

INTEGER INCHAR;

 

CHANGE IN$

{

INCHAR = 0;

WHILE(INCHAR <> 'A')

INCHAR = GETC(IN$);

 

// continue processing.

}
