* 09-02-83 RN initial version
* 08-31-84 RN modified to use new, blazing fast fwrite
* 07-01-87 JCR made return values conform to ANSI [MSC only]
* 09-24-87 JCR Added 'const' to declaration [ANSI]
* 11-05-87 JCR Multi-thread version
* 12-11-87 JCR Added "_LOAD_DS" to declaration
* 05-18-88 JCR Error return = EOF
* 05-27-88 PHG Merged DLL and normal versions
* 06-15-88 JCR Near reference to _iob[] entries; improve REG variables
* 08-18-89 GJF Clean up, now specific to OS/2 2.0 (i.e., 386 flat
* model). Also fixed copyright and indents.
* 02-15-90 GJF Fixed copyright
* 03-19-90 GJF Made calling type _CALLTYPE1, added #include
* <cruntime.h> and removed #include <register.h>.
* 03-26-90 GJF Added #include <string.h>.
* 07-23-90 SBM Replaced <assertm.h> by <assert.h>
