Whats the diff between COBOL-IMS and PLI-IMS.

I know cobol and PL/I are different programming languages.I know how to code DLI calls in COBOL. but how can I achieve this in PL/I

Thanks in advance

dlI calls in pl/I:

plItdlI: parm_count,
function code,
pcb_name,
seg_io,
ssa1,
.......,
ssa15;

here parm count indicates the number of parameters using in the call.
function code represent the type of call (gu, ghu like that),
pcb_name indicates the name of pcb name on which dlI call is issued,
seg_io - segment input output area,
ssa - segment search area.

using cobol:

call cbltdlI using function_code,
-----,
------,
------;

here parm_count is not necessary in cobol.

Hi sudhaaa,

You are aware of how to code DLI calls in COBOL right in the similar way to code in PL/I with small changes

Program Changes
1.Use PLITDLI instead of CBLTDLI
2.Need to Use ParmCount while it is option in COBOL.
3.A lot of Built-in Functions are available in PL/I and not in COBOL

No change in PROC's and JCLS.

Hi Sudheer and KS,

Thanks for your replies. I hope you well known about Linkage section in COBOL.Here in PL/I, how can achieve this.
This is not a IMS question, but I'm posting here because in IMS using LINKAGE SECTION is very common(for PCB-MASK). So, How can I achieve this.

Thanks in advance.

Sudhaaa.
