READLN

 The READLN procedure reads lines of data from a TEXT file.

 Syntax:

    READLN [[( [[file_variable,]] {variable-identifier
    [[:radix-specifier]]},... [[, ERROR := error-recovery]]) ]];


 The 'file_variable' is the name of the file variable  associated
 with  the  TEXT  file  to  be read.  If you omit the name of the
 file, the default is INPUT.

 The 'variable-identifier' is the name of the variable into which
 a   file  component  will  be  read;  multiple  identifiers  are
 separated by commas.  If you do not specify any  variable  name,
 READLN skips a line in the specified file.

 The 'radix-specifier' is one of the format values BIN,  OCT,  or
 HEX.  These values, when used on a variable identifier, read the
 variable in binary, octal, or  hexadecimal,  respectively.   You
 can use a radix specifier only when reading from a TEXT file.

 The 'error-recovery' specifies the action  to  be  taken  if  an
 error occurs during execution of the routine.  By default, after
 the first error, the error message is printed and  execution  is
 stopped.

 The file must be in inspection mode before READLN is called;  it
 remains in that mode after the procedure's execution.

 The READLN procedure reads  values  from  a  TEXT  file.   After
 reading   values  for  all  the  listed  variables,  the  READLN
 procedure skips over any characters  remaining  on  the  current
 line  and  positions the file at the beginning of the next line.
 The values need not all be on a single  line;  READLN  continues
 until  values have been assigned to all the specified variables,
 even if this process results in the reading of several lines  of
 the input file.

 EOLN returns TRUE after a READLN procedure only if the new  line
 is empty.

 See the "HP Pascal Language Reference  Manual"  for  a  complete
 description of the READLN procedure.
