set @fullName = AttributeValue("fullName") /* value from attribute or DE column in send context */
set @fullName = "SFMC ESSENTIALS" /* or a literal value */

set @fullNameProperCase = ProperCase(@fullName)

fullName: %%=v(@fullName)=%%
<br>fullNameProperCase: %%=v(@fullNameProperCase)=%%

Output

fullName: SFMC ESSENTIALS
fullNameProperCase: Sfmc Essentials

<br>Random: %%=v(@random)=%%

Output

set @lastName = AttributeValue("lastName") /* value from attribute or DE column in send context */
set @lastName = "Jackson" /* or a literal value */

set @fullName  = Concat(@firstName, " ", @lastName)
