Hello,
I purchased the book, read through it, but I have a thick skull.
Perhaps I can get some advice here on two questions about converting
formula expressions that look like "basic" syntax...
IF REP_DTE > '2001-01-01' AND ATOTAL>100 THEN
H-CAPRESTATE
ELSE
IF REP_DTE < '2001-01-01' THEN
ACCTG_CNG + ACCTG_ERR_CRCT
END IF
END IF
Into a flat format that looks like Excel formula syntax...
IF( AND(REP_DTE > '2001-01-01',ATOTAL>100), H-CAPRESTATE, IF(REP_DTE <
'2001-01-01', ACCTG_CNG + ACCTG_ERR_CRCT)
I tried writing a few grammar files, but all have had various runtime
issues.
Here are my questions...
1. Is ANTLR the right tool for this job? (I don't have much time.)
2. If it is the right tool, is there already a grammar that will get me
most of the way there?
Thanks in advance for any advice.
Regards,
Frank Font
