Hello,
How to use the SUBSTR function in the DEFINE context ?
The documentation says :
SUSTR(inlength,infield,start,end,xxxxxxx,outfield)
I have tried to use this but without success .
Regards
Philippe

You will find an example of SUBSTR in the program AUTORDB.FEX
which comes with FOCUS (assuming you have the RDB interface)
and it works.

The xxxxxx in your example needs to be the length of the substring:
normally END - START + 1.

DEFINE FILE DATAFILE
NEWFIELD/A10 = SUBSTR(80, ADDRESS, 1, 10, 10, NEWFIELD);
END
Where ADDRESS is an 80 char alpha field, the above will let NEWFIELD
eq the first 10 chars of the ADDRESS field.
