| Option name | @PROCESS directive | Description |
|---|---|---|
| -qalign | ALIGN | Specifies the alignment of data objects in storage, which avoids performance problems with misaligned data. |
| -qbindcextname | BINDCEXTNAME | Controls whether the -qextname option affects BIND(C) entities. |
| -qctyplss | CTYPLSS | Specifies whether character constant expressions are allowed wherever typeless constants may be used. |
| -qddim | DDIM | Specifies that the bounds of pointee arrays are re-evaluated each time the arrays are referenced and removes some restrictions on the bounds expressions for pointee arrays. |
| -qdescriptor | None. | Specifies the XL Fortran internal descriptor data structure format to use for non object-oriented entities in your compiled applications. |
| -qescape | ESCAPE | Specifies how the backslash is treated in character strings, Hollerith constants, H edit descriptors, and character string edit descriptors. |
| -qextern | None. | Allows user-written procedures to be called instead of XL Fortran intrinsics. |
| -qextname | EXTNAME | Adds an underscore to the names of all global entities. |
| -qlog4 | LOG4 | Specifies whether the result of a logical operation with logical operands is a LOGICAL(4) or is a LOGICAL with the maximum length of the operands. |
| -qmodule | None. | Specifies that the compiler should use the XL Fortran Version 8.1 naming convention for non-intrinsic module files. |
| -qport | PORT | Provides options to accommodate other Fortran language extensions when porting programs to XL Fortran. |
| -qswapomp | SWAPOMP | Specifies that the compiler should recognize and substitute OpenMP routines in XL Fortran programs. |
| -qxflag=oldtab | XFLAG(OLDTAB) | Interprets a tab in columns 1 to 5 as a single character (for fixed source form programs). |
