MFS_READ - Read from a file

Read the specified number of bytes from the file to a buffer location. 
Calling Sequence   

int far pascal MFS_READ(pcData, pusLength)

char far * pcData;
unsigned long far * pusLength;

pcData is a pointer to the data area to be read into. The data area is 
guaranteed to be below the 1-Meg boundary. 
pusLength is a pointer to a word which on entry specifies the number of 
bytes to be read. On return, it is filled in by the mini-FSD with the 
number of bytes successfully read. 
If no error is detected, a zero error code is returned. If an error is 
detected, a non-zero error code is returned. 
The current file position is advanced by the number of bytes read.
