New subroutine MX_SRCHPATH (191) searches for a file in the system path.
xcall MIAMEX, MX_SRCHPATH, file, foundpath
Parameters
file (String) [in]
filename to search for (no wildcards or directory)
foundpath (String) [out]
returns "" if not found, else the full path.
Comments
The search path is system dependent, but normally includes the current directory, the directory from which the A-Shell executable was loaded, plus all the directories included in the PATH environment variable.
One use would be to check whether a particular external command exists before attempting to launch it via HOSTEX.SBR.
