Hi ,all


I meet an problem about the cobol subprogram calling , if i call an subprogram from a main program ,the sub program can access any file on mainframe? or the sub 's all dates must delivery from main program thought the link section? if the sub can access file directly , how should i write statement in main program or JCL?

Thanks

hi wooyoo,

you can do two things,thru the linkage section you can pass all the file parameter from mainprogram to subprogram or you can do with external declaration of file.
