GDDM V3R2 Base Application Programming Reference
SC33-0868-02

Versions of the VS FORTRAN compiler earlier than Release 3.0 cause extra parameters to be generated for character items in CALL statements, when the LANGLVL(77) compiler option is in effect; GDDM does not accept these extra parameters. Therefore, to prevent these extra parameters being generated, the SC compiler option must be specified.

The current release of VS FORTRAN does not generate these extra parameters, and so the SC compiler option is not required.

Parameters must be declared as:

Fullword integer

INTEGER*4

Halfword integer

INTEGER*2

Floating-point

REAL*4

Character

String literals or numeric data array initialized with string literals

Arrays

A one-dimensional array. (You can use a multidimensional array if it causes the correct storage mapping. FORTRAN arrays are stored in column-major order.)

Structures

No FORTRAN application data structure is generated by GDDM-IMD.

For example:


     CALL FSINIT
     CALL GSSEG (0)
