Actions
Parameter actions are divided into:
Iteration parameter actions
General parameter actions
De last group can also be used in the manipulation of other Substitution-variables (System-variables, Template-variables and Context-variables).
Iteration parameter actions
| Actions | Description |
|---|---|
| BEGIN_PARAMETERS {Block_name} | Read the parameters starting in block {Block_name} |
| END_PARAMETERS | Read the next block of parameters. |
| REWIND_PARAMETERS | Restart with the first block of parameters (Deprecated). |
General parameter actions
| Actions | Description |
|---|---|
| INC_PARAMETER {PAR1} | Increment Parameter {PAR1}. |
| ADD_PARAMETER {PAR1}{PAR2} {PAR3} | Add Parameter {PAR2} to {PAR3} and assign the result to {PAR1}. |
| SUBTRACT_PARAMETER {PAR1}{PAR2} {PAR3} | Subtract Parameter {PAR3} from {PAR2} and assign the result to {PAR1}. |
| MULT_PARAMETER {PAR1}{PAR2} {PAR3} | Multiply Parameter {PAR2} with {PAR3} and assign the result to {PAR1}. |
| DIV_PARAMETER {PAR1}{PAR2} {PAR3} | Divide Parameter {PAR2} by {PAR3} and assign the result to {PAR1}. |
| END_PARAMETER | NA |
| BEGIN_PARAMETER {PAR1}{PAR2} | Assign to parameter {PAR1} the value of {PAR2} . |
| UPPER_PARAMETER {PAR1}{PAR2} | Assign to {PAR1} the value of {PAR2} , after {PAR2} has been converted into UPPERCASE. |
| INC_PARAMETER {PAR1} | Increment {PAR1} with 1. |
| PAR_EMPTY {PAR1} | Make the value of parameter empty. |
The action BEGIN_PARAMETER is used to assign a value to a parameter. Assignment in Action scripts can only be done using the value of other Substitution-variables (Systeem-variables, Datadictionary-variables, Template-variables, Parameter-variables).
This dictated the structured defenition of variables. Parameters thus are strict with respect to assignment.
If you like the header, it can be found here.
If you are using firefox, put your cursor over the logo. But for some reason IE does not like image rollover effects. Its not that big of a deal.
