Umgang mit Umgebungsvariablen

In ARCO it is possible to create, read and delete entries in the Windows Registry, in this way the user can have specific environmental variables for his use.

Setting and Reading Environmental Variable

This is used to set general variable that can be read from all the different part programs.
The typical use is to set a path to copy result files from all the programs.
An example of application is:

• From one part program the program set the environment folder:

$$ Declare the base Variable


DECL/CHAR,200, STR1

STR1=ASSIGN/'C:\Report Folder')

$$ Use the command SETENV/ to create the entry in the registry


SETENV/'MY_REPORT_FOLDER', STR1

• From all the other programs the program read the folder and output there:

$$ Declare the base Variable


DECL/CHAR,200, STR2

$$ Use the command GETENV/ to read the entry from the registry


STR2=ASSIGN/GETENV('MY_REPORT_FOLDER')

$$ Declare the base , the dummy point, the tolerances and build the output


DECL/CHAR,200, STR2

DECL/CHAR,200, STR3

STR3=ASSIGN/CONCAT(str2,'output.mea')

DID(OUT_FILE)=DEVICE/STOR,STR3

F(q)=FEAT/POINT,CART,00,0,0,0,0,1

FA(q)=FEAT/POINT,CART,00,0,0,0,0,1

T(CORTOL_1)=TOL/CORTOL,XAXIS,-0.1000,0.1000

T(CORTOL_2)=TOL/CORTOL,YAXIS,-0.1000,0.1000

T(CORTOL_3)=TOL/CORTOL,ZAXIS,-0.1000,0.1000

OPEN/DID(OUT_FILE),FDATA,V(TEXT),OUTPUT,OVERWR

OUTPUT/FA(Q),TA(CORTOL_1),TA(CORTOL_2),TA(CORTOL_3)

CLOSE/DID(OUT_FILE)

Deleting Environmental Variable

This is used to clean an Environmental general Variable that has been previously set.
An example of application is:

• From one part program we set the environment folder:
  

$$ Declare the base Variable


DECL/CHAR,200, STR1

STR1=ASSIGN/'C:\Report Folder')

$$ Use the command SETENV/ to create the entry in the registry


SETENV/'MY_REPORT_FOLDER', STR1

• From another part program we clear the environment folder:
  

$$ Use the command DELENV/ to remove the entry from the registry


DELENV/'MY_REPORT_FOLDER'
