Input Format Lines
Each format line has an input value, from the input file field, followed by an equal sign, then the field label that it represents.
For example if this were a Sex variable and your input data contained a "1" representing males and a "2" representing females, the lines would be:
1 = Male
2 = Female
When all the format lines have been edited press the OK button to return to the Variable Specification dialog with the changes.
