To my knowledge It starts with 1.

if you try storing some value in Array(0) it will produce erroneous results

i thnk it will give OC7 when u try to access array(0)....as i faced once the same.

i don't think you will get a soc7 while accessing it. the data willnot get stored as expected. still u can display them. May be u got SOC7 while doing some manipulations with it.

i was getting when some how program was moving array(0) to a another working storage varibale, since that area is not defined and u r trying to access it, so in that case won't it give OC7?? Please clarify my doubt...

Hi,

S0C7 can happen due to

1. Numeric operation on Non-numeric data
2. Un-initialized working-storage
3. Coding past the min/max allowed subscript
4. etc.

The move you had mentioned could belong the the 1) category in the above list.

Please correct if I'm wrong.

Cheers,
