HELP NEXTCHAR A. Sloman Aug 1988
nextchar(<procedure>) -> <character>
Where <procedure> is an item repeater created by *INCHARITEM, NEXTCHAR
returns the next character that would have been used by the item
repeater. The command
<character_or_string> -> nextchar(<procedure>)
can be used to modify the internal buffer of the item repeater; the
character or the characters in the string are added to the buffer.
NEXTCHAR can also be applied to *ITEMREAD to access or alter the buffer
of the character repeater used in the expansion of the dynamic list
*PROGLIST.
For further details of input/output procedures, see REF * SYSIO.
For information on the use of ITEMREAD and PROGLIST, see REF *PROGLIST.
