SYS_GetExecutableDir is executed, by default, in the Agent process, not the Silk Test Classic process. To affect the host process, use the function with the hHost notation or machine handle operator. For more information about the machine handle operator and hHost, see Machine handle operator.
SYS_GetExecutableDir appends the appropriate directory delimiter for your platform.
A similar function, GetExecutableDir, runs within Silk Test Classic and therefore returns the directory of the Silk Test Classic (partner.exe) executable.
