Numeric Equates

Numeric equates

thinBasic allows you to refer to numeric constants by name. Those constant values are called equates.

Equates data type

Equates declaration has the following syntax:

%EquateName = NumericExpression [As NumericDataType]

Where the optional parameter NumericDataType can be any of the allowed numeric data types: BYTE, INTEGER, WORD, DWORD, LONG, QUAD, SINGLE, DOUBLE, EXTENDED, CURRENCY.

If not NumericDataType is specified, default type will be assumed to be LONG.

Examples

Some equate declaration example:

%MAXPIECES = 32

%NPARAM = 3

%NTYPE = 1

%RANK = 2

%FILE = 3

%KING = 1

%PAWN = 2

%MAXVALUE = 0.999 AS EXT

Restrictions

1.	Numeric equates name must start with percent sign %

2.	Unlike variables, you can use an equate on the left side of an assignment statement only once.

3.	If an equate has already been created, subsequent attempts to assign a new value will fail but no error will be generated
