**xcall MIAMEX, MX\_HASHFILE, path, hash1, hash2, hash3, hash4**

MX\_HASHFILE (MIAMEX 25) returns a hash code for the file specified in the path argument. The hash code consists of four integer values.

**Parameters**

_path_  ([String](string.htm.md))  \[in\]

specification of file being hashed. May be in native or DevPPN format. 

_hash1...4  _([Num](num.htm.md))  \[out\]

receive the four parts of the hash. Each part if an integer from zero to 255.

**Comments**

The hash algorithm is the same as that used by the AMOS DIR/H command.

For display purposes, the AMOS and A-Shell hash-total formats treat the numeric values as octal.

**Example**

The following example illustrates the use of this function to display a hash total in the format used by DIR/H:

MAP1 HSHSTR,s,4 \! Octal string byte

MAP1 STRING'HASH,s,15 \! Display format hash-total (###-###-###-###)



xcall MIAMEX,MX\_HASHFILE,THISIPATH,HASH1,HASH2,HASH3,HASH4

xcall MIAMEX,MX\_OCVT,HASH1,3,OT\_MEM+OT\_OCT,HSHSTR

STRING'HASH = HSHSTR+"-"

xcall MIAMEX,MX\_OCVT,HASH2,3,OT\_MEM+OT\_OCT,HSHSTR

STRING'HASH = STRING'HASH+HSHSTR+"-"

xcall MIAMEX,MX\_OCVT,HASH3,3,OT\_MEM+OT\_OCT,HSHSTR

STRING'HASH = STRING\_HASH+HSHSTR+"-"

xcall MIAMEX,MX\_OCVT,HASH4,3,OT\_MEM+OT\_OCT,HSHSTR

STRING'HASH = STRING'HASH+HSHSTR

print STRING'HASH
