       gets - Read a line from a channel

1mSYNOPSIS0m
       1mgets 4m22mchannelId24m ?4mvarName24m?


1mDESCRIPTION0m
       This  command reads the next line from 4mchannelId24m, returns everything in
       the line up to (but not including) the  end-of-line  character(s),  and
       discards  the end-of-line character(s).  If 4mvarName24m is omitted the line
       is returned as the result of the command.  If 4mvarName24m is specified then
       the line is placed in the variable by that name and the return value is
       a count of the number of characters returned.

       If end of file occurs while scanning for an end of  line,  the  command
       returns  whatever  input  is available up to the end of file.  If 4mchan-0m
       4mnelId24m is in nonblocking mode and there is not  a  full  line  of  input
       available, the command returns an empty string and does not consume any
       input.  If 4mvarName24m is specified and an empty string is returned in 4mvar-0m
       4mName24m  because  of  end-of-file  or because of insufficient data in non-
       blocking mode, then the return count is -1.  Note that  if  4mvarName24m  is
       not specified then the end-of-file and no-full-line-available cases can
       produce the same results as if there were an input line consisting only
       of  the end-of-line character(s).  The 1meof 22mand 1mfblocked 22mcommands can be
       used to distinguish these three cases.
