Define

Syntax:

#define SYMBOL = VALUE

This directive defines a symbol by indicating the expression (VALUE) it represents. The same can also be done with the equ construct for numeric expressions as illustrated in previous examples.

Actually, support for equ was introduced in H1ASM for compatibility with such "traditional" construct. However, the #define directive is conceptually more robust and more powerful in practice since it allows for symbolic strings too.

The previous example could also be written this way:

#define   MSG_TABLE         = 0x800
#define   ERR_MSG_F_NOFOUND = $File not found
#define   ERR_MSG_S_OV      = $Stack overflow

:MSG_TABLE

#data     ERR_MSG_F_NOFOUND
#data     ERR_MSG_S_OV
