+*
+*Purpose:
+* defines _spawnl() - spawn a child process
+*
+*Revision History:
+* 04-15-84 DFW Re-do to correspond to similar exec call format
+* 12-11-87 JCR Added "_LOAD_DS" to declaration
+* 11-20-89 GJF Fixed copyright, alignment. Added const to arg types
+* for pathname and arglist. #include-d PROCESS.H and
+* added ellipsis to match prototype.
+* 03-08-90 GJF Replaced _LOAD_DS with _CALLTYPE2 and added #include
+* <cruntime.h>.
+* 07-24-90 SBM Removed redundant includes, replaced <assertm.h> by
+* <assert.h>
+* 09-27-90 GJF New-style function declarator.
+* 01-17-91 GJF ANSI naming.
+* 02-14-90 SRW Use NULL instead of _environ to get default.
+* 07-16-93 SRW ALPHA Merge

+*int _spawnl(modeflag, pathname, arglist) - spawn a child process
+*
+*Purpose:
+* Spawns a child process.
+* formats the parameters and calls spawnve to do the actual work. The
+* new process will inherit the parent's environment. NOTE - at least
+* one argument must be present. This argument is always, by convention,
+* the name of the file being spawned.
+*
+*Entry:
+* int modeflag - defines which mode of spawn (WAIT, NOWAIT, or OVERLAY)
+* only WAIT and OVERLAY are currently implemented
+* char *pathname - file to be spawned
+* char *arglist - list of argument
+* call as _spawnl(modeflag, path, arg0, arg1, ..., argn, NULL);
+*
+*Exit:
+* returns exit code of child process
+* returns -1 if fails
+*
+*Exceptions:
