1750 HEIDENHAIN Technical Manual MANUALplus 620
8.38 USES Statement (USES)
Syntax: USES <file name>
Operands: None
Action:
You can use the USES statement in the main program to link other files. Files
that are linked with USES can themselves also use the statement to link
further files. It is also permissible to use the USES statement to link a single
file to several other files. The code for this file is generated only once. The
USES statement requires a file name as an argument. The USES statement
only links a file; it does not run the file's program code. The USES statement
cannot be compared with a CM statement. The linked files must therefore
contain individual modules that you can then call with the CM statement.
Example:
USES PLCMOD1
USES EPRUPG
USES RAMPLC
Linking of files:
Function STL
Main program PLCMAIN.PLC
Link the file for spindle control. USES SPINDLE.PLC
Link the file for tool change. USES TCHANGE.PLC
