3.4 File and Program Management
Examples:
● Passive file system or GDIR:
– NC notation: _N_WKS_DIR/_N_MYNCPROGS_WPD/...
– EES notation: WKS.DIR/MYPROGS.WPD/...
● External program memory:
– /abc
– /ab_c.def
– /ab c1.def
– /a b c .d11
– /abc.def/ghi.klm
File name
The following rules apply to the file names:
● Only for addressing in NC notation do file names begin with the domain identification "_N_".
● The next two characters should be either two letters or an underscore followed by a letter.
Note
If this condition is satisfied, then an NC program can be called as subprogram from another
program just by specifying the program name. However, if the program name starts with
digits, the subprogram call is then only possible via the CALL statement.
● The following characters can be any combination of letters, digits and "_".
● File extension:
– The file extension must consist of three letters/digits.
– They are separated with "_" (NC notation) or "." (EES notation) from the file names.
Examples:
● Passive file system or GDIR:
– NC notation: _N_SUB1_SPF
– EES notation: SUB1.SPF
● External program memory:
– Part 1
– _Part1
– Part_1.spf
– Part1.mpf
