PB/CC constants (also known as equates) are defined by prefixing the name of the constant with a "%" character. MSBASIC and VB define constants with the CONST keyword. The MSBASIC/VB compiler then does type conversions at the point of use, if the constant's type was not specified. That overhead does not happen (and is not necessary) with PB/CC. String equates are specified with a leading "$" character.
However, the MACRO facilities in PB/CC offer a way to retain the CONST syntax in your code, while maintaining the low overhead advantage of PowerBASIC. For example:
MACRO CONST = MACRO
...
CONST Something = 1&
CONST Something_Else = 2???
CONST AppTitle = "My Application"
...
PRINT AppTitle, Something
During compilation, the CONST keyword is replaced by the MACRO word, which dynamically creates a new macro that, in turn, defines a constant.
