Hi Allu,

No questions is less improtant, all the questions are equally important. Feel free to as any kind of question on SAS. There are many good members in this group who will provide there valuable suggestions to you.

With regard to your question,

value statement is used to create the formats to convert the numeric to character and character to character.

An informat is created to read and convert the data values using the invalue statement. it is mainly used to read the character data and convert to numeric.

In the above case invalue will work better.

proc format;

invalue  convert

'A+' = 100

'A' = 96

'A-' = 92

'B+' = 88

'B' = 84

'B-' = 80

'C+' = 76

'C' = 72

'F' = 65;

run;

data grades;

input @1 ID $3.  @4 Grade $;

/*format grade convert.;*/

new_grade=input(Grade,convert.); *To create the numeric value;

datalines;

001A-

002B+

003F

004C+

005A

;

run;

Thanks,
