SUPPORT / SAMPLES & SAS NOTES
Problem Note 42118: Values containing an ampersand are treated as macro variables by the SGPLOT, SGPANEL, and SGSCATTER procedures
 |  |  |  |
The following warning message might be received when using the SAS/GRAPH® Statistical Graphics procedures SGPLOT, SGPANEL, and SGSCATTER:
WARNING: Apparent symbolic reference XXXX not resolved.
The problem is most likely to occur when the ampersand symbol is included as part of an axis or variable label. For example:
proc sgplot data=sashelp.class;
scatter x=weight y=height;
label height='&testlabel';
xaxis label='&testaxis';
run;
The graph output contains the text as expected, but there is currently no way to prevent the warning message from being produced.
