Example 3: Implicit/explicit "LF"
a, writing into the passive file system with implicitly generated "LF"
Program code
...
N110 DEF INT ERROR
N120 WRITE(ERROR,"/_N_MPF_DIR/_N_MYPROTFILE_MPF","MY_STRING")
N130 WRITE(ERROR,"/_N_MPF_DIR/_N_MYPROTFILE_MPF","MY_STRING")
N140 M30
Output result:
MY_STRING
MY_STRING
b, writing into an external file without implicitly generated "LF"
Program code
...
N200 DEF STRING[30] DEV_1
N210 DEF INT ERROR
N220 DEV_1="LOCAL_DRIVE/myprotfile.mpf"
N230 EXTOPEN(ERROR,DEV_1)
N240 WRITE(ERROR,DEV_1,"MY_STRING")
N250 WRITE(ERROR,DEV_1,"MY_STRING")
N260 EXTCLOSE(ERROR,DEV_1)
N270 M30
Output result:
MY_STRINGMY_STRING
c, writing into an external file with explicitly generated "LF"
The following must be programmed in order to achieve the same result as under a:
Program code
...
N200 DEF STRING[30] DEV_1
N210 DEF INT ERROR
N220 DEV_1="LOCAL_DRIVE/myprotfile.mpf"
N230 EXTOPEN(ERROR,DEV_1)
N240 WRITE(ERROR,DEV_1,"MY_STRING'H0A'")
N250 WRITE(ERROR,DEV_1,"MY_STRING'H0A'")
N260 EXTCLOSE(ERROR,DEV_1)
N270 M30
Output result:
MY_STRING
MY_STRING
