Description:
This routine
should only be used when implementing a routine which will be passed as the SOURCE argument to
AST_CHANNEL. It should be used to pass back (to the AST library) each line of text read from the
external data source. One such line should be passed back in this way for each invocation of the source
routine.
Invocation
CALL AST_PUTLINE( LINE, L, STATUS )
Arguments
LINE = CHARACTER
(
)
(Given)
A character string containing the line of input text which has been read.
L = INTEGER
(Given)
The number of characters in the input line, which may be zero. If there is no more input
available (e.g. an end of file has been reached), this value should be set negative and this will
terminate the read operation on the
Channel.
STATUS = INTEGER (Given and Returned)
The
global status.
