&GLOBAL-DEFINE Preprocessor Directive
Globally defines a compile-time constant (preprocessor name).
SYNTAX
preprocessor-name
The preprocessor name (compile-time constant) that you supply. Progress reserved keywords are allowed, but cannot be used in preprocessor expressions.
definition
A string of characters (or preprocessor references that evaluate to a string of characters) whose content the preprocessor substitutes for preprocessor-name during compilation. If the definition is longer than one line, a tilde (~) at the end of the first line indicates continuation to the next line.
EXAMPLESIn this example, the preprocessor name
MAX-EXPENSE
is defined as the text string “5000".
Wherever the reference
{&MAX-EXPENSE}
appears in the source code, the preprocessor substitutes the text string “5000". For example, the preprocessor changes this line of code:
to this line:
NOTES
- You must place the &GLOBAL-DEFINE directive at the beginning of a line, preceded only by blanks, tab characters, or comments (/* comment */).
- The syntax of the &GLOBAL-DEFINE and &SCOPED-DEFINE directives are identical but these directives are used differently. For more information, see the chapter on the preprocessor in the Progress Programming Handbook .
