7.If population is a macro variable obtained in the prior programs, take highly notice this variable is a character value. So if you use it in next calculation, try to avoid the statements like this: IF COUNT=&TRTA THEN PCT=’100’. As the var...
2.Associate compatible data with the template using theSGRENDERprocedure to create the graph. SGRENDER语法: 注意: Variable namescan be hard-coded in the template, such as “Height”, “Weight”, or “Age”, as in the SASHELP.CLASS data set. TheSGRENDERprocedure will validate thatvariable name...

Macro variables are just a text substitution mechanism. When you execute SAS code, the value of the macro variable (a text string) is substituted into SAS code (where the macro variable was in the code), and this substitution of macro variable value into the code MUST produce valid working ...
