5.11
Details on the position of the short text, position of the input/output
field
Overview
The short text and graphic text, as well as the input/output field and unit text, are each
treated like a unit, i.e., position settings for short text apply to the graphic text and settings for
the input/output field and to unit text.
Programming
The configured position entry overwrites the default value, i.e., only one value can be
changed. If no position settings have been configured for subsequent screen form elements,
then the position settings for the preceding screen form element are applied.
If no positions have been specified for any dialog elements, the default setting is applied. By
default, the column width for the short text and input/output field is calculated for each line
based on the number of columns and maximum line width, i.e.,
c olumn width = maximum line
width/number of columns.
The width of the graphics and unit text is predefined and optimized to suit the requirements
of programming support. If graphics or unit text has been configured, the width of the short
text or I/O field is reduced accordingly.
The order of short text and I/O field can be reversed by position settings.

Use of strings
Strings
Strings can be used as part of the configuration. These allow text to be displayed
dynamically or different texts to be chained for the purpose of code generation.
Rules
The following rules must be observed with regard to string variables:
● Logic operations are processed from left to right.
● Nested expressions are solved from the inside outwards.
● No distinction is made between uppercase and lowercase type.
● String variables are generally displayed left justified.
Strings can be deleted simply by assigning a blank string.
Strings can be appended after the equality sign using the operator "<<". Quotation marks (")
in the string are represented by two successive quotation mark symbols. Strings can be
checked for equality in IF instructions.
