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.

I have an access application I inherited that uses the WdMfDsp.ocx control to get data from Rumba.
After upgrading to windows 7 we now are getting an error message.

"A license is not available at this time. general license error occurred -2"
 
followed by another message

"The operation of the Objectx Mainframe display control object failed.
The OLE server may not be registered."

I'm new to using this type of work, any suggestions would be appreciated.

Have got some links/guides from BTan previously for OWASP & Java.

Q1:
I'll now need secure programming guides/standards for Cobol (the ones used in IBM mainframes/AS400)
esp those with good practices like:
a) proper input validation (eg: to mitigate against XSS & injections)
b) avoid hardcoding passwords &  IP addresses in the codes
c) enforcing session timeouts (session idle is forced to logout)
d) exceptions handling (so that under exceptions, the program doesn't bomb out, possibly to OS)
e) ...

Q2:
For .Net & Java, we used Fortify to scan the codes;  is there equivalent scannners for Cobol?

 The most common is use of OWASP recommended ESAPI in various lang for secure coding adopted by organisation practices https://www.owasp.org/index.php/Category:OWASP_Enterprise_Security_API

I am trying to build a DDL statement off a COBOL program layout.  I have never used COBOL syntax before.

I AM NOT SURE WHAT PIC X(26) , PIC XX OR PIC X MEAN?
Example:
Cobol layout
TIMESTAMP                  PIC X(26).                        
CPIS_CMPY_CDE              PIC XX.                        
DCH_CAPSIL_CMPY_CDE            PIC X  

New ddl statement in Teradata
TIMESTAMP                  char(26)                        
CPIS_CMPY_CDE           ?                
DCH_CAPSIL_CMPY_CDE            ?

i HAVE INCLUDE A TEXT FILE OF THE COBOL LAYOUT I TRYING TO CREATE DDL STATEMENT.

Hi Experts,

I have to fill a field in a displayfile, by fieldname
When I put the cursor on a field and press one Function key, I have to store some data from that field.
When I put the cursor on a field and press another Function key, I have to put some data into that field.

After pressing the Fxx key I know the fieldname and screenposition, but I need at least the position in the screenbuffer.


Thanks

I have a list of Mainframe libraries -- and I have to identify which ones are in PDSE format.

Is there a command that I can use in batch that will show this?

I have procedures to run LDR and LU commands in batch -- and hoping to find a command to identify library types.

Thanks for the help,

Hello,

I've heard many times that Fortran is a programming language still usefull, even so it is more than fifty years old. Also I 've read that it was mainly applied to IBM mainframes for bank and finance businesses,

Is it still in that way? Is it only used for banks and for programming mainframes?
