Problem:

When compiling or running the following program with no special options, we receive the below error codes.

IDENTIFICATION DIVISION.
PROGRAM-ID. ROGERW.
ENVIRONMENT DIVISION.
DATA DIVISION.
WORKING-STORAGE SECTION.
01  ALLP  PIC X.
PROCEDURE DIVISION.
CALL 'csort' USING ALLP.
STOP RUN.

error code: 161, pc=2B, call=1, seg=0

161 Illegal intermediate code

Resolution:

The problem is that csort is an entry point in the Micro Focus runtime library. There are a few more to be aware of as entry point names with the following prefixes:

"_"

"mF"

"MF"

"mf"

"CBL"

"cob"

"CEE"

"ADIS"

"STRIPE"

"fs"

"FS"

"CEE"

"CCI"

"oo"

"STRIPE"

"PARSE"

"XML"

"Invoke"

"scum" (stands for Sooty Communications Underlying Module)

C standard library function names may also cause errors. Single byte names where the character has binary representation are also best avoided:

>

= 0x80

Following is a list of specific names (this list is very incomplete) which also may cause errors:

EXTFH

csort

csortv

extsm

EXTSM

CHECKFIL

direct

PANELS

charset

animator
