Paul,
I have just done the following calculation - some way to spend a vacation, eh? If you create a method or call a function to do the following...
---
nSeconds=INT(SECONDS()+(nn*60)) && nn being the number of minutes.
nHours=INT(nSeconds/3600)
nMins=INT((nSeconds-(nHours*3600))/60)
IF nHours>23
nHours=0
ENDIF
RETURN PADL(LTRIM(STR(nHours)),2,'0')+':'+PADL(LTRIM(STR(nMins)),2,'0')
---
This will return a string as "09:10" or "23:48" - I've just tested this in VFP5 (it has just hit midnight here and it went correctly from 23:59 to 00:00. If you want to do the date also, just put dNextDate=DATE() at top and in the IF nHours>23 bit, put dNextDate=DATE()+1. Regards,
