Definition of Nested Formats and Validation

This script defines two formats using PROC FORMAT. The 'loads' format defines labels for value ranges. The 'couple' format demonstrates a nesting technique: it applies the 'loads' format for values between 5000 and 10000, handles a specific value (2), and applies a standard 'comma6.' format for other cases. A Data Step _null_ is used to test these formats on internal data.

Type : CREATION_INTERNE

Data is defined directly in the script via the CARDS statement.

PROC FORMAT

Explanation :
Definition of 'loads' and 'couple' formats. Note the use of square brackets [ ] in 'couple' to dynamically call another format ('loads') or a system format ('comma').

1	PROC FORMAT ;
2	value loads
3	5000-<6000 = 'Over 5,000'
4	6000-<7000 = 'Over 6,000'
5	7000-<8000 = 'Over 7,000'
6	8000-<9000 = 'Over 8,000'

DATA STEP

Explanation :
Execution Data Step that does not create an output table (_null_). It reads in-line data (CARDS) and writes the formatted value of 'x' to the log via the PUT statement.
