Solved: evaluate TRUE

Cobol, the acronym for COmmon Business Oriented Language, is one of the oldest programming languages, designed for business data processing needs. Despite its age, it continues to hold significant relevance in the modern IT landscape due to its extensive usage in the backend systems of many financial institutions and government agencies.

Problem Evaluation: The TRUE in Cobol

Cobol differs from most modern languages in its Boolean values. Rather than using TRUE and FALSE as Boolean flags, it uses non-zero and zero values respectively. This might seem confusing, especially for those used to other languages. Hence, it becomes essential to understand and evaluate the use of TRUE in Cobol.

To evaluate TRUE in Cobol, or display it, you would typically set it up in your working storage, and use DISPLAY upon the condition that you required to evaluate. The use of TRUE in Cobol can be made clear in the following steps:

PROGRAM-ID. EvaluateTrue.

01 bool-value PIC X.

move “Y” to bool-value
if bool-value = “Y”
display “The boolean value is TRUE”

Cobol Libraries and Functions

Cobol doesn’t have libraries like other languages such as Python or Java. However, it does contain procedures which could be considered similar. Procedural elements in Cobol, defined within the PROCEDURE DIVISION, are the equivalent of functions in languages like JavaScript or Python. Explaining the procedures of Cobol would require a rather extensive amount of information which goes beyond the scope of this article. Nonetheless, Cobol remains as an interesting and valuable language to study and understand.

Fashion: A reflection of style and self-expression

Fashion is not just about the clothes we wear, it tells a story about who we are and what we represent. It is a means of self-expression that allows us to portray our identity and uniqueness. Fashion essentially is wearable art, where designers take inspiration from various elements such as color, patterns, fabric, and trends to create pieces that are meant to be admired and worn.

The runway presents these fashion trends in a way that exhibits designers’ vision for that season. The catwalk is the place where fashion designers make a statement about their brand and style. It serves as a platform demonstrating the projected fashion trends, whether it be the colors, prints, fabrics, accessories, or the overall look.

An Overview of Fashion Styles

There are numerous fashion styles, each with its unique vibe and history. These styles often reflect the societal and cultural shifts of their time. A few popular ones include:

  • Classic Style: Known for its timeless elegance. Favoring simplicity, clean lines, and high-quality fabrics. Examples include tailored blazers, pencil skirts, little black dresses, and well-fitted trousers.
  • Casual Style: Comfort-focused style that is underscored by relaxed outfits and laid-back accessories. It includes denim jeans, casual button-downs, t-shirts, and comfortable shoes.
  • Trendy Style: Style with a futuristic approach, offering what’s “in” at the moment. It’s influenced by the high fashion and runway trends.

Trends and color combinations

Each year, color trends change, and the Pantone Color Institute plays a significant role in this process. For instance, the color for 2021 is ‘Ultimate Gray and Illuminating’, a combination of dull, dependable gray and the bright yellow of lemon skin. It’s a metaphor for the way the fashion world and everyone else is looking to 2021.

Just as with colors, fashion trends are always evolving. One constant, however, remains: mixing and matching different styles, patterns, and colors in a way that reflects personal style and self-expression, which will always be in vogue.
