Language enhancement, compiler edit 932: XOPEN now supports RANDOM and ISAM 1.x files. Also, XOPEN supports the option of expressing the flags argument as an expression rather than as a binary variable.
XOPEN for RANDOM:
XOPEN #ch, fspec$, RANDOM, recsiz, {,flags}
In the case of RANDOM, you may use the flag FDVF_FORCED (&h0010) to convert it to RANDOM'FORCED (i.e. shared).
XOPEN for ISAM 1.x:
XOPEN #ch, fspec$, ISAM'INDEXED, recsiz, {,flags}
In the ISAM 1.x case, as with ISAMA, you can use the flag FDVF_EXCLUSIVE (&h0800) to convert from ISAM'INDEXED shared to ISAM'INDEX'EXCLUSIVE.
For completeness, here is the complete list of flags that can be used with XOPEN:
