Scratch Variable Definition

DEVELOPER

Trail: PROIV Documentation > Developer > PROIV Developer > Developing Functions > Scratch Variable Definition

You can open this window to define scratch variables via the Scratch Variable Maintenance icon on the PROIV Developer toolbar or the Logic Editor Toolbar.

If you enter the name of a new scratch variable in the logic editor, a definition window is opened automatically.

The Fields in this Window:

Variable - Enter the variable name.

Length - The length in characters.

Dimension - The dimension (number of elements if the variable is an array).

Description - A description.

Properties - Select a variable and click Properties to display the length, dimension and description of the selected variable in a Properties window.

In earlier PROIV development environments it was possible to create a scratch variable with default properties: alphanumeric ($) variables were assigned 30 characters and numeric variables (#) were assigned 12 characters. To avoid unnecessary use of workspace – and accidental mistyping of variable names – all scratch variables are now defined in PROIV Developer.
