Hi Gregory,
this I knew it,
but your message has made to see one me solution (slow),
at least for the expressions.
CLEAR
FOR K=1 TO ALINES(aExp,PreprocessExpr('PRECONSTANT1>3,PRECONSTANT1*m.x+INT(m.y)','#DEFINE PRECONSTANT1 1'),',')
? aExp[m.k]
NEXT
FUNCTION PreprocessExpr(sExp,sDefines)
PRIVATE sTempFile,sCode
STORE SYS(2023)+'\_#####COMPILE####_.tmp' TO sTempFile
=STRTOFILE(m.sDefines+CHR(13)+[=]+m.sExp+[,=],m.sTempFile)
COMPILE (m.sTempFile)
STORE STREXTRACT(FILETOSTR(FORCEEXT(m.sTempFile,'err')),'=',',='+CHR(13)) TO sCode
ERASE FORCEEXT(m.sTempFile,'*')
RETURN m.sCode
ENDFUNCFabio
