SpGetBootdrive

Returns the drive letter of the volume the system was booted from. In contrast to spQuerySysInfo('QSV_BOOT_DRIVE') a letter with appended colon is returned.

The function is equivalent to the following Rexx Statement:

D2C(C2D('A')-1+spQuerySysInfo('QSV_BOOT_DRIVE'))||':'

Syntax: bootdrive = spGetBootdrive ( )

Returns: Drive letter of boot volume followed by a colon

Example Code:

/* bootdrv.cmd (spUtils Example Code) */
/* The env variable specified as argument is set to the drive letter of */
/* the boot volume, or if called without parameter, writes it to stdout */
