There are many computer languages, and they have been evolving from machine language into a more natural way of writing. Languages are generally classified into machine language (direct machine code); assembly (using mnemonics to present the instructions to be translated later into machine language by an assembly program); procedural languages, also known as high-level languages (HLL) (Pascal, FORTRAN, Algol, JCL, COBOL, REXX, PL/I, Basic, and C are common), along with several other types. Mainframe programming is largely done in the procedural languages.

Hi
I have been handed a legacy project that has being abandoned by the original designer as he is retiring and wants no more to do with it so i am inheriting the system it ws designed some 22 years ago so its a system that looks like a db3 dos system.
i have spoken to him once and he said that the db is written in dbl and that the program is written in a mixture of cobol and fortran so he said.
the whole lots sits on a unix box which happens to be un-seeable on via windows explorer,
now i do not want to play too much on the network i am not a unix boffin, but do have access to the back ups which i am guessing hold the DBL files which hold the data files that i wish to access.
********************  what i need
so what i need to do, is to access the dbl tables in the unix section or off the backups and get access to these tables and then extract the information out of them so that i can rebuild the system that i will be building, but first i need to see the tables and then go from there.
so not being a unix person you can see what  i need
i know that dbl is supposed to to be short for data base language but thats it not sure that the guy was not leading e down the garden path as he has the system hidden from the client for the last couple of decades with the support guy the only one that has the remote dial in for the network so
what do you think can you lend me in the right direction
thanks for any help in advance
