Undeclared Variables in a .PRG

[AUGE_OHR]

hi,

did you get

Ambiguous reference, assuming memvar '_HMG_SYSDATA'

it is the same as

Ambiguous reference '_HMG_MAINWINDOWFIRST'

so the Solution is also the same

Code: Select all

MEMVAR _HMG_SYSDATA, _HMG_MAINWINDOWFIRST

Hello Jimmy, The alert disappears, but I am left with the question of why ?
They are not variables that I created, and those of the system are declared in their respective internal functions.
It does not matter as long as everything works well, but I wanted to learn more.

Very grateful for all your contributions and help !

Hidden in its commands, HMG is using non declared public variables.
The MEMVAR directive declares them, so the warning vanishes.
