Introduced in v3.0, Preemptive: yes
| Parameter | Type | In/Out | Description |
|---|---|---|---|
| Context | Longint | → | Execution context |
| Varname | Text | → | variable name |

Description
The command hmX_SET VARIABLE adds a variable and a it’s value to an execution context. Pass the variable name into the parameter varname. The name of the variable is not case sensitive. So myvariable is the same as MyVariable. Like in 4D. The following types of variables are currently supported:
- Is Real (1): use valuenum
- Is Text (2): use valuetext
- Is Date (4): use valuedate
- Is Boolean (6): valuenum must be 1 for true, or 0 for false
- Is LongInt (9): use valuenum
- Is Time (11): valuenum is the number of seconds
If a variable with the variable name exists, the variable will be overwritten.
Example
The following example adds a variable vt_myvariable into the context with the value “My value”:
hmX_SET VARIABLE($context; "vt_myvariable"; Is real; "My value"; 0; !00-00-00!)
