Changing Environment Information
The following example uses GETASSIGNTEXT to obtain a file name:
?GUARDIAN GETASSIGNTEXT
CHARACTER*63 filename
INTEGER error
error = GETASSIGNTEXT ('TANDEMNAME', filename, 1)
Changing Environment Information
The group of SMU routines that begin with PUT and the ALTERPARAMTEXT routine
allow you to change environment information. The PUT routines are the exact
counterparts of the GET routines. Each PUT routine enables you to insert a new value
into a PARAM, ASSIGN, or startup message.
The difference between PUTPARAMTEXT and ALTERPARAMTEXT is that
ALTERPARAMTEXT enables you to insert trailing blanks in the new parameter value.
