2.Bad Subscript/Index
3.Read/Write attempt to unopened file
4.Move data to/from unopened file
5.Missing parameters in called subprogram
SOC7 abend may be due to the following reasond
1.Numeric Operation on Non-numeric data
2.Coding past the maximum allowed subscript.
3.Un-initialize working storage.
Please let me know if there more reasons for the above mentioned abends.

soc7-Caused due to bad data, in case of numeric data we are moving non-numeric,in case of numeric comparison we are finding space
SOC4 means subscript being out of range. This is because of compiler option.
Default is nossrange we have to change it for ssrange....
SOC7 means uninaialized numeric field. For SOC7 if we are doing numeric opretion which field is defined as non-numeric.
