Subject: Maximum input line size?
Content-Type: text/plain; charset=us-ascii
Hi,
A question from a SAS newbie: what is the maximum input line size in
SAS, and how can you control it? I'm running into problems when I have
a large number of input variables. To show you a concrete example, the
following piece of code with ten variables works just fine:
options nocardimage ls=64 nodate;
data filter;
input (F01 F02 F03 F04 F05 F06 F07 F08 F09 F10 ) (6.3) filter $4.;
cards;
1.000 0.019 0.000 0.001 0.002 0.000 0.002 0.006 0.019 0.011 F01
0.040 1.000 0.057 0.021 0.041 0.009 0.002 0.016 0.025 0.003 F02
0.009 0.072 1.000 0.060 0.031 0.012 0.003 0.007 0.003 0.001 F03
0.007 0.039 0.068 1.000 0.058 0.055 0.026 0.016 0.002 0.005 F04
0.001 0.058 0.034 0.056 1.000 0.073 0.025 0.036 0.019 0.012 F05
0.000 0.012 0.023 0.058 0.090 1.000 0.046 0.040 0.006 0.004 F06
0.000 0.003 0.007 0.025 0.022 0.048 1.000 0.091 0.024 0.014 F07
0.005 0.012 0.009 0.013 0.025 0.031 0.085 1.000 0.075 0.030 F08
0.008 0.018 0.000 0.004 0.012 0.005 0.013 0.044 1.000 0.038 F09
0.008 0.006 0.004 0.003 0.013 0.005 0.001 0.035 0.034 1.000 F10
;
However, when the number of input variables is large, for example,
when the input line has 120 variables
input (F01 F02 ... F120 ) (6.3) filter $5.;
1.000 0.019 ... 0.011 F001
SAS gives error message on input line (line 3)
1 options nocardimage ls=64 nodate;
2 data filter;
WARNING: Truncated record.
and after a lot of junk output prints
ERROR: No CARDS or INFILE statement.
Since this depends only on the number of variables / length of input
line, I must be violating some constraint.
Any help is much appreciated. Thank you in advance.
