[F90:]subroutine gSetStrUnderscore(und) integer, intent(in) :: und
Arguments
und
String underscore switch
= GOFF,
Underscore off (default)
= GON,
Underscore on
Description
The routine gSetStrUnderscore() switches underscoring of subsequent strings on or off. Underscoring affects all string output using gDisplayStr(), gDisplayStrPolylineBy2D(), gDisplayStrPolylineTo2D() and gFitCharStr().
When underscoring is switched on a solid line is drawn by GINO, using an appropriate line width related to the character height. The line is drawn 0.4*character height below the base line of the character string.
If und is neither GOFF or GON, a warning message is output and underscoring is switched off.
Underscoring can be temporary switched on and off using the *S and *A escape sequences respectively. These are described under gDisplayStr().
