This Section gives full specifications for the user-level TRANSFORM routines. The following notation is used to specify the types of routine arguments:
| Notation | : | Fortran type |
| L | : | LOGICAL |
| I | : | INTEGER |
| R | : | REAL |
| C | : | CHARACTER() |
| ? | : | Unspecified, dependent on the data type being processed. |
| () | : | A 1-dimensional array of one of the above types. |
| (,) | : | A 2-dimensional array of one of the above types. |
| L | : | A 1-dimensional LOGICAL array, with TRN__MXCLS9 elements, to contain classification information. |
| C | : | A CHARACTER argument to contain a precision specification of maximum length TRN__SZPRC.9 |
| C | : | A CHARACTER(DAT__SZLOC)10 argument containing an HDS locator. In some routines where this is an input argument, a blank string (of any length) may be substituted to specify different routine behaviour; the individual routine descriptions give details. |
| C | : | A CHARACTER argument specifying an HDS name string of maximum length DAT__SZNAM.10 |
9The symbolic constants TRN__MXCLS and TRN__SZPRC are defined in the include file TRN_PAR.
10The symbolic constants DAT__SZLOC and DAT__SZNAM are defined by HDS.
