The Instructions Block of Macros

Scroll Prev Up Next More

The last section of any macro is the instructions block, whose purpose if to determine the values of sRESULT and bRESULT (and, optionally and rarely, n_RESULT).


Note that these 2 variables are initialized to '' and false, respectively, but if you do not set any value for them, then a warning message will be generated.


The instructions block begins with the begin keyword and ends with the end keyword, and is where most of the work of the macro happens.

    // bResult will be true if the date of the token is a Sunday
    bResult = (WeekdayOf(n_TokenDate) == 7)
    // replace the macro token by the token without the *XX
    sResult = '[' + IntToStr(n_TokenDayValue) + s_TokenRoot + ']'
