As I understand input processing, yes you are mistaken !
Have you tried it ?
The data step should hold the current infile buffer until the input
following an input without a trailing @ sign.
Have you tried it ?
So -shame on me- it doesn't work, because the lrecl option needs a
number and won't take a variable name. I'm ever, too hopeful !
I was trying to ensure that any input record was guaranteed space in the
output buffer. I had presumed I could copy lrecl value in that way.
There is a limit of 32k on the output buffer linesize.
The following code works for input records up to 32k
139 %let config= %sysfunc( getoption( config ));
140 data _null_;
141 infile "&config" ls=32767 flowover ;
142 file "corefound" ls=32767 ;
143 input @'core' ;
144 put _infile_;
NOTE: The infile "C:\business\data\sas\config.ts045.sas" is:
NOTE: The file "corefound" is:
NOTE: 233 records were read from the infile
The minimum record length was 0.
The maximum record length was 81.
NOTE: 12 records were written to the file "corefound".
The minimum record length was 29.
The maximum record length was 44.
NOTE: The DATA statement used 0.05 seconds.
On this platform win95, LRECL would allow numbers greater than 32k, to
be defined, but short of two passes through the input, I don't know of a
foolproof source for the value necessary to guarantee accomodating the
Has anyone the answer ?
