Transitioning to isCOBOL : Transitioning from ACUCOBOL-GT : Compiler options
Compiler options
• When compiling source files of an ACUCOBOL-GT application, the following options should always be used:
-ca -cnlz -smat -wlu
• If the ACUCOBOL-GT version is 7.0 or later, the following option should also be used:
-dvexta=32
• If you didn't use -Cf option with the ACUCOBOL-GT compiler, then the following option should be used with the isCOBOL compiler:
-crv
• If you didn't use -Ck option with the ACUCOBOL-GT compiler, then the following option should be used with the isCOBOL compiler:
-cko
• If you didn't use -Za option with the ACUCOBOL-GT compiler, then the following option should be used with the isCOBOL compiler:
-m1
• If you didn't use -Zz option with the ACUCOBOL-GT compiler, then the following option should be used with the isCOBOL compiler:
-cudc
• If your application uses characters that take more than one byte in memory (e.g. Chinese characters) and you want string operations such as INSPECT, STRING and UNSTRING to work byte-wise rather than character-wise, then the following option should be used as well:
-b
• If you have level 78 items defined just below group items to measure their size, then the following option should be used:
-s78c
• If you have $ signs in COPY statements in order to reference environment variables in the copybook path, then the following option should be used:
-sevc
This is a typical case where -s78c is necessary:
01 group1.
   03 data-item1 pic x(10).
   03 data-item2 pic 9(3).
78 group1-sz      value length of group1.
• Some ACUCOBOL-GT options are available in isCOBOL with the same name and produce the same effect. Some others are not available in isCOBOL, but their effect can be obtained anyway. The following table lists the known ACUCOBOL-GT options along with their equivalent in the isCOBOL environment, if available:

Use -dci compiler option
-Dcm
The same option is available in isCOBOL.
Use -dcm compiler option
-Dcn
The same option is available in isCOBOL.
Use -dcn compiler option
-Dcr
The same option is available in isCOBOL.
Use -dcr compiler option
-Dd31

In order to have the same precision on the last decimal digits, use -cfp36 compiler option
-Df
Use -cv compiler option
-Di

-Ds
The same option is available in isCOBOL.
Use -ds compiler option
-Dv=#
Use -dv=# and -dvexta=# compiler options
-Dw32
Default behavior using isCOBOL.
-Dw64
Use -d64 compiler option. Note that only USAGE POINTER data items are affected.
-Dz
The same option is available in isCOBOL.
Use -dz compiler option
-e
Use -eo=folder compiler option.
isCOBOL allows to specify the destination folder for error files, but not the file name. Files are always named ProgramName.err
-Fa
Use -efa compiler option.
isCOBOL generates dictionaries in XML format. Acucobol-GT’s XFD and isCOBOL XML are not compatible
-Fm
The same option is available in isCOBOL.
Use -fm compiler option
-Fo
Use -efo=folder compiler option
-Fx
Use -efd compiler option.
isCOBOL generates dictionaries in XML format. Acucobol-GT’s XFD and isCOBOL XML are not compatible
-Ga
Use either -d or -dx compiler options
-Lf
The same option is available in isCOBOL, but isCOBOL list files are not in ANSI format by default.
Use -lf and -la compiler options combined
-Lo
Use -lo=folder compiler option.
isCOBOL allows to specify the destination folder for list files, but not the file name. Files are always named ProgramName.list
-Ls
Use -ld compiler option
-o
Use -od=folder compiler option.
isCOBOL allows to specify the destination folder for object files, but not the file name. Files are always named PROGRAMNAME.class
-Rc
The same option is available in isCOBOL.
Use -rc=word1,word2 compiler option
-Rw
The same option is available in isCOBOL, but the usage is slightly different.
In isCOBOL the option can’t be repeated, so all the reserved words must be specified at once separated by comma. E.g. the following Acu options:
-rw word1 -rw word2
are translated to isCOBOL as follows:
-rw=word1,word2
-S# (where # is the number of columns for each tab)
Use -stl=# compiler option
-Sa
The same option is available in isCOBOL.
Use -sa compiler option and avoid using -smat
-Si
Add IF Directive to the source
-Sl
The same option is available in isCOBOL.
Use -sl compiler option.
-Sp
The same option is available in isCOBOL.
Use -sp=folders compiler option
-Sr
Use -stl=8,4
-St
The same option is available in isCOBOL.
Use -st compiler option and avoid using -smat
-Sx
Add IF Directive to the source
-v
The same option is available in isCOBOL.
Use -v compiler option
-Va
Not available in isCOBOL.
isCOBOL has an option named -va, but it’s for other purposes
-Vc
Default behavior using isCOBOL
-Vh
The same option is available in isCOBOL.
Use -vh compiler option
-Vl
Default behavior using isCOBOL, unless -vh is used
-Vu
The same option is available in isCOBOL.
Use -vu compiler option
-Vx
The same option is available in isCOBOL.

-Zd
Use either -d or -dx compiler options
-Zi
The same option is available in isCOBOL.
Use -zi compiler option
-Zo
Use -efo=folder compiler option
-Zr#
Use either -pt0, pt1 or -pt2 compiler options according to your needs
-Zx
Use -efd compiler option.
isCOBOL generates dictionaries in XML format. Acucobol-GT’s XFD and isCOBOL XML are not compatible
-Zy
The same option is available in isCOBOL.
Use -zy compiler option
-Zz
Default behavior in isCOBOL
The latest ACUCOBOL-GT compilers support conditional compilation through the use of special constructs in the COBOL source file and by accepting command-line arguments that turn on compiler directives and set constants to values. This feature is implemented in compatibility with Micro Focus. Refer to Compiler options in the Transitioning from Micro Focus guide for details about how to obtain the same result with isCOBOL.
