New Text Item: Inconsistency in SAS data step
Certain characters effect the way a quoted string is interpreted. For
example '...'x indicates the quoted string is hexadecimal, '....'d
indicates a date, and '....'t indicates a time string. In your example,
SAS is trying to read 't1 ='t1 as a time string. Why not just use <
PUT t1= ; >?
By the way, a little bird told me that "n" will be added to the list of
characters with special meaning when at the end of a quoted string. In
version 7, it will indicate that the quoted string is a SAS variable
name so that SAS variable names can contain Blanks,$#@. etc. This will
permit SAS to use names from other data sources without using an
"ACCESS" to map the columns to SAS names.

Dear SAS-lers,
After some trial and error I discovered a inconsistency (or even a bug?)
in a SAS
data step.
Please take a look at the the following SAS code:
data _null_;
y1=0;
put "Y1="y1;
t1=0;
put "T1=" t1; *** space between character string and name of variable;
run;
data _null_;
y1=0;
put "Y1="y1;
t1=0;
put "T1="t1; *** NO space between character string and name of
variable;
run;
This code produces the following LOG:
1 data _null_;
2 y1=0;
3 put "Y1="y1;
4
5 t1=0;
6 put "T1=" t1;
7 run;
Y1=0
T1=0
8
9 data _null_;
10
11 y1=0;
12 put "Y1="y1;
13
14 t1=0;
15 put "T1="t1;

ERROR 22-322: Expecting one of the following: NAME, NAME.NAME, #, +, @.

NOTE: SAS Institute BV, 1217 KR Hilversum, The Netherlands
So, SAS produces an error if there is no space between the character
string and
variable name T1. This is NOT the case for variable Y1.
Please let me know what you think about this.
I'm running SAS 6.08 on VMS version 5.5
